How to make gasoline and diesel fuel out of crude oil

hi this is professor scott norman from pittsburg state university and we are in the department of automotive technology in our fuels lab and part of this class that we do this mobile fields class is we have our our students doing activity where they uh distill crude oil uh to to make uh gasoline straight run gasoline and some diesel fuel so they'll separate the um the uh the actual crude oil into it some some simple fractions and so um so we do this lesson as a simple way to explain how destination works and how how from crude oil you can separate out the different fractions to make gasoline or kerosene or jet fuel or diesel fuel or really whatever you want to we're going to make try to make some straight run gasoline and to make some um some diesel fuel so in order for that to happen i got to set up some some equipment so i'm kind of setting up the equipment before the students get here today and so let me just explain what i have right here as far as to set this up i have a trap makita or electric heater that i am i have that i'm going to heat up the the crude oil in and i got a a distillation uh beaker is what i have and so it's a round bottom um beaker that um holds 250 milliliters of a fluid and it has a tube coming out the end and so what i have already here is i have a 200 milliliters of crude oil that that a student will um it's from a barton county uh here in the area and students will um help me get crude oil on occasion and it will last me quite a while if i only do 200 milliliters at a time but i'm going to take my oil and you want to start off with a known quality of oil because you want to know what percentage of your fuel and again crude oil is very runny it's not like mortal oil mortar oil is separated out of the crude oil so it's um it's very very runny and it's a very dark black gold is what they said right and so and so we're going to let that settle in my um in my flask while i'm getting everything set up but i have a cork in this and what's gonna happen is i'm gonna put this on the heater and i'm gonna this cork is gonna go into a condenser it's probably the best way to say that and i'm gonna stick this in where the tube is you know in the condenser at least maybe uh an inch or so maybe two inches at the most and get my heating mechanism set up really level and i'm gonna put this fixture on it to kind of hold it so i don't knock it over because that would be very bad because we're going to heat up this oil pretty good so okay so what i am going to do next is i'm going to put a oh it's a little piece of wire that we fabricated but what's going to happen is i'm going to put this um jack chain in here and it and it's the jack chain starts kind of right here in the um in the tower of the flask not down where the oil is boiling but this helps um the oil um condense and help it vaporize when it comes up in this taller area here okay and so i got two different chains and so that chain is too long let me go get my shorter chain so i'll be back okay so i have a shorter chain i'm going to put in now and again that helps the vapors from the oil come up and helps condense and i may try to get two of them in there if i think they'll fit nope only one's gonna fit the reason why i can't go up too far is because i need to put a thermometer in there and my thermometer goes all the way up to 700 degrees because that's what the temperature of the oil could be as we're boiling it so right now i'm reading you know right around 70 degrees here at this spot here 700 degrees is up up towards the top of this we're going to be boiling the oil to um maybe 500 degrees uh to distill the um the diesel fuel but i'm gonna set this up where my bulb for my thermometer the top of the bulb of the thermometer is right at the bottom of this spot right where my fingers at right there where this piece of um tubing is coming out so it's important to set the thermometer up at the right spot all right so what we're going to do is that we're going to heat up the oil the oil is going to cook for a while it's going to heat up heat up heat up and then it's going to start boiling as it starts boiling the vapors are going to come up the vapors can't come out because it has a cork and the vapors are going to come through this um this tube it's going to go through my condenser now my condenser is um i've got a thermometer in there so i can kind of see what the temperature of the condenser is but it's full of ice and water so i can get some of my ice out so you can see the ice on there but it's ice water is all it is so there's my ice and it's filled up to the top with water and i got a thermometer in there because i like to see what the temperature of it is and you know it's around 40 degrees right now i have a spare one that i want to show you that it looks like so you can see what all it is is that you got yourself a so over here you got yourself a tube the tube goes all the way from one end and it comes out of the other side over here so you have a tube that is in a big box that's full of water and isolated so as the um as the um the vapors are going through the tube uh you know the tube is angled down from the top to the bottom it's going to flow downhill uh the the the the fuel vapors are going to condense and as they condense they're going to come out of this tube right here and so this tube right here is where i'm going to capture my my fuels that are coming out and so when i first heat this up to 100 degrees i'm going to get very light fuels coming out you know maybe some butane if butanes is there some some pentane as it heats up more and more then the hexane starts coming out and so forth and so the fuel is going to start dripping out and it's going to drip out clear and so i have um a a beaker you know 100 milliliter beaker i'm not going to fill this thing full of gasoline maybe i'll be lucky to get 40 maybe 50 milliliters out of out of this sample just depending upon how much light gasoline i still have in the sample but i have it in ice water so there's ice water water also in this guy right here because what's happening is as that fuel is coming in that that that that lighting fuel i want to protect my vapors i don't want any of those vapors that just vaporize out at room temperature and so i have a you know i have a piece of um uh oh cork we'll call it on the top of this to try to help seal the top of it with some weight on it so as the um as the distillation process is happening and it's dripping i'm able to capture there now at some point i'm going to switch over from making uh gasoline the diesel fuel maybe i do that at 350 degrees maybe i do that at 375 maybe i do a 400 i let the students typically decide when they want to stop making gasoline when they start making diesel fuel but at some point i will swap this out so i'll i'll pop this out i'll put a cork in it to make sure i'm not losing any of my vapors and i'll put my new beaker underneath it and i'll start collecting diesel fuel and so it's a fun project for the students it's fairly easy to do you do need a little bit of equipment to get it started but once you got it set up it's fun to see the students uh reaction as far as how much gasoline do they think we can make out of this uh versus a diesel fuel hello this is professor scott norman and i'm back with the lesson on distillation uh there was a wrinkle in our plan to do the distillation with our students today as it got down to negative 15 degrees overnight and it's now a snow day so for those of my international friends it's a negative 15 degrees fahrenheit not celsius so pretty cold hasn't been coated around this coat around here for the last 30 years so so obviously no school we call that a snow day and so um we're going to do this lesson remotely without students anyway um as far as crude oil uh there's been a lot of talk with my students about uh the the internal combustion engine going away and uh 2030 2035 there's um there's uh states in the united states there's also countries saying that they're not going to allow any new sales of the internal combustion engine and what's that going to do with crude oil production what's that going to do with refineries obviously we're not going to be using as much gasoline but i just wanted to point out that that that there is literally thousands of different products made from crude oil besides uh gasoline and a diesel fuel and so when you start looking at our economy and you know we are the oil industry or the oil world right now as far as as far as what we use you know you think about the computer and the headphone and my calculator and pretty much everything that i have around me is made out of some type of a crude oil basis as far as synthetics clothes and stuff like that so plastics you know and so and so i don't see that industry going away anytime soon obviously we're not going to be burning uh hydrocarbons in our internal combustion engine that makes co2 that produces a global warming but obviously there's a lot of other products that we can still use that crude oil for so on this distillation process um what i wanted to do with this slide see if that i'm not sure what there we go so um so so this is kind of how we have set up here so i have my 200 milliliters of crude oil in the in the heating flask and i got a a cork on it with a thermometer the thermometer this particular picture is a little crew that thermometer needs to be that just a little bit lower than where it's currently at but that's okay but as this uh oil is heated up you know it's gonna start boiling and so first it's gonna you know it's good it's gonna be at 100 degrees and then it's going to slowly warm up to well at least i'm looking at it right here at the thermometer um the the actual vapor is coming up is going to be at 100 degrees and then it's going to go up slowly to 120 degrees and that's going to slowly go up to 150 degrees and so what we'll see is that even though this oil is boiling the amount of vapor is coming off of it the all the light in stuff so you know when you start looking at the light hydrocarbons that are in the oil that could maybe be some butane that could be some pentane you know anything that's under 100 degrees of the actual boiling point that's going to come off first and then the heavier hydrocarbons is going to come off next you know the the c6s and the c7s and the c8s and so on and so so they're gonna the gases are gonna come up and then you're gonna go down my uh tube here to the uh through the condenser that i have the uh the ice and the uh the water in and those vapors are going to condense into a liquid form and then it's going to drip out into my graduated cylinder here and so we're going to be able to measure how much gasoline we comes out and then at some point we're going to take this graduated cylinder and we're going to replace it with another one to start to start collecting the the heavier hydrocarbons and so you know it's a fairly simple process you know i got a fairly fancy condenser but there's a lot of different types out there that you could use i wanted to show you next on here so when you start looking at the distillation of crude oil you know under 90 degrees you know room temperature i typically call that you're going to have butane propane ethane methane all the lighter uh hydrocarbons anything that's lower than a c4 hydrocarbon uh it is going to come out uh you know at room temperature and so so when we start looking at gasoline we typically start collecting that at around 90 degrees so right now my oil is at 70 degrees and so as i heat it up to 90 degrees you know 96 97 degrees uh if there's any pentane in it then that's going to start coming out right away as far as uh the actual vapors and so the oil is going to be boiling when the vapors in that in that flask gets up to 100 degrees if there's any pentane in it it's going to start coming out right away now now my oil has been around for a few years now so my guess is that probably all my c5s have long evaporated even my c6s may have evaporated already so i'm not expecting to get any drops of fuel in my graduated cylinder until way above 100 degrees maybe 120 degrees it may be 130 degrees i don't know about but we're going to watch and see when the first drop comes in and that tells me what's my lightest gasoline i have in this crude oil and and and we say that you know as far as good quality gasoline it's on the light side the heavier gasoline well there's more btus per gallon we'll say but it's not a better quality for you by any means so so so we're going to do straight run gasoline so so typically you know they'll at the at the refinery you know anywhere between 90 to 220 degrees uh as far as the vapor temperature coming off that um that boiling oil you can get anywhere between c5 and c 10 hydrocarbons yeah you know we would call that light gasoline you know gasoline we would definitely want to be using in the wintertime when it's negative 15 degrees here in kansas uh starting at around 220 degrees you know give or take a little bit uh we have this stuff that's called naptha which is heavy gasoline if you want to call it that you know a lot of people will will will actually combine the c5 all the way up to c12 and just call it gasoline but here i broke it out in between um light gasoline and heavy gasoline and so the heavier gasoline you know could go all the way up to let's say 315 degrees so my c10 and my c12s and so so the key is is that to snap there right here i could put this into the um straight run gasoline maybe in the summertime where i want a little bit heavier gasoline uh on it it can handle it uh uh i'm worried about the volatility and the evaporation of my smaller lower hydrocarbons and plus again that has more btus per gallon uh starting around 3 15 degrees give or take you know then we start collecting the seeds 12 hydrocarbons which is the kerosene and so that goes from c12 up to c15 if i get above 450 degrees well then i'm starting to collect diesel fuel uh which is in between the c15 the c18 range of hydrocarbons and the lubricating oils which is um you know getting pretty hot now so the vapor is coming off that boiling crude oil is at 650 degrees around 800 degrees is my c18 c20 hydrocarbons which is you know lubricating all those motor oils and stuff like that so so what we're going to do is that we're going to heat up our our flask and we're going to measure the temperature the vapor is coming off and so we're going to collect anything that we can you know any any any of the lighter stuff c5 c6 if there is anything in there and at some point we're going to switch over to a diesel fuel so maybe we switch it all over at 315 uh maybe we switch it over 300 maybe we switch it over to 325 it just depends on how close we're watching that thermometer and really um you know it's you know we could take some of this kerosene that we're making you know in the wintertime and and put it over here to this diesel fuel so so maybe i'm going to stop it i don't know 300 we'll say and i'm going to collect up to 300 degrees for a gasoline switch over to diesel fuel and so i'm going to put this kerosene into the diesel field to make a more number one diesel fuel i'm going to call that uh for the winter time so so so we have a little bit of volatility on a diesel fuel we're worried about you know the diesel fuel gelling up when it's negative 15 degrees around here and so so again depending upon how i cut my fuel my fraction really depends upon what the um what the refinery wants to do do they want to make more gasoline do they want to make more diesel fuel do they want to separate out this kerosene for maybe some heating oil um uh i could go to the hardware store and and i could actually buy nafta you know c10 to c12 hydrocarbons which is used as like a solvent so i could use do that if i wanted to make that uh at the refinery when you're looking at a barrel oil what you have to realize is that we're doing this process right here where we're taking let's say one barrel of oil you know 42 gallons we'll call that of crude oil going in and and the key is is that when you look at how much gasoline is in that 42 gallons of oil you don't have a lot you know you're looking at you know uh less than five percent gasoline uh jet fuel diesel fuel they have it combined it's one area right here you know you're looking at you know to a little bit more but again it's it's right around about five percent so the bottom line is is that there's not a lot of um so out of that 200 milliliters of crude oil i have i'm gonna get you know about this amount of um of gasoline and diesel fuel so it's not a lot now if you take your your uh your oil tour to a to a modern refinery and they go through all the modern refinement process of you know cracking the um the uh the oil and and hydrogenating it then the percentages are a lot different and so you know when you go to a a modern refinery you know you're going to get a lot more gasoline out of your oil in fact if you put 42 gallons in you're gonna actually get 44 gallons out because they they're adding hydrogen to the um to the or to the oil think of it like popcorn you know you put a small amount of popcorn in the microwave and it comes out a lot bigger volume is what it is well we're adding hydrogen to the oil and it kind of you know kind of puffs it out and makes it more and so we're actually getting more oil out but when you look at those percentages of 44 gallons coming out and you know half of it is gasoline so you know so obviously that's the united states is a big deal if you're over in europe maybe you're going to want to make more diesel fuel and so you're going to take a little bit of this gasoline production and make it over here and again that's the refinery that's going to be their choice as far as uh what they want to do with their oil do they want to make more gasoline with it do they want to make more diesel fuel with it and so we'll go ahead and get started with the destination of the soil we started the heating process for the oil so i turned the um the electric heater on a position of four so not very hot and it's been on for about five minutes now and i can see that the oil is starting the the boil just a little bit i can start seeing the liquid start to move my thermometer if i take a look at my thermometer it's reading no 75 76 77 degrees somewhere around there so it just started to rise so it did start at 75 and so it's slowly starting to go up i got my uh bath of ice water down to about uh about 40 degrees my graduating cylinder here that uh it's empty um i have an ice bath there that's around 40 degrees also and so all we're doing is waiting for the vapors to start to come out and see what the first drop is so so we'll watch very carefully over here to see when the first drop comes out and when the first drop comes out we're going to come over here and we're going to look and see what the temperature is and so that's going to be the start of the actual distillation process of collecting gasoline the thermometer is reading a little bit over 100 degrees right there so maybe 105 degrees maybe 110 degrees and i have nothing coming out of the um nothing coming out of the center yet so i know that i don't have any pentane coming out but we'll watch carefully because as this is going up to uh it's maybe going up to 125 i'm gonna turn down the heat just a little bit we're going to watch and see when our first drop is i'm currently at 150 degrees so there's my 150 degree mark right there and i can see vapors and condensation happening inside my tube right here but nothing's coming out into my graduating center quite yet so again i knew that a lot of my lightings were already gone because i had to sample crude oil for a while but at 150 degrees there's still no dripping coming out of my cylinder so i'm watching my cylinder right here and i'm seeing when i see the first drop and and i got my cylinder in an ice bath to help keep those uh those vapors if there was any um low volatility vapors from evaporating um there probably isn't in the sample but again we don't have any dripping quite yet as soon as it starts dripping it's going to get going pretty quick if i take a look at my my thermometer over there it's about 175 is where we're currently at and we still don't have anything at all so again this is a pretty heavy sample of crude oil again if i was pulling this out of the ground i would be um again this is like a field test they would do they do real quick see hey how much of this crude oil is heavy versus light in this particular sample it's a pretty heavy crude oil again there's not a lot of light in gasoline in this oop i just saw a drip i just saw one little drip see if we could try to get another one going another drip right there and we're right at about a little bit under a hundred let me see i'm going to say one 190. there goes another drip so you can start seeing another drip there so 190 was our first drip on that here's a close-up of the flask boiling you can see that the fluid in there the oil in there is boiling never gently and we're measuring the temperature of the vapors inside the tube and you can kind of see where the position of the of the thermometer is to the tube that's run into the condenser if i take a look up and see what my temperature my thermometer is you can see it's a little bit above 200 so maybe 210 somewhere in there okay we can take a look at it and see the condenser and you can see the ice water going through the condenser so you can see going down through the tube the condenser so my thermometer on the condenser is reading around 40 degrees so a nice bath of ice then as it's coming out of the tube and coming to my graduated cylinder look down here and see where we're at so we can start seeing a little bit oh we can see a drip there and we started seeing a little bit of gasoline being accumulated there another drip there and i have it going kind of slow right now so i don't want to heat up the the temperature of the oil too much where it goes from 200 to 300 with inches a couple minutes i wanted to you know slowly go through there and so so i i know that i if i have 200 milliliters that if i get to the 10 milliliter mark that's gonna be uh five percent uh if i go to the um the the 20 mark the two the 20 milliliter mark that's going to be 10 uh of my initial um sample of 200 milliliters and so i see it against you a little drip so so my guess is is that we don't have a lot of gasoline in this particular sample that we're going to get a pretty small uh sample of gasoline because all the light ends have evaporated off pretty much again we didn't get our first drip until to 190 degrees and so we'll take this up um to maybe you know somewhere a little bit above 300 degrees and then we'll switch over and start collecting diesel fuel there's another drip so again we got it going very slowly right now see the dripping coming out of the the tube there and we got the um we got something on the top of it to try to help keep any lighting vapors if there was any from escaping up there was another trip right there so we're at about at 250 degrees right now and if i'm looking to see how much we have we have probably about oh i don't know i would say two we're gonna call it three milliliters so far so my dripping is getting kind of faster now i'm just gonna go drip drip drip drip so you can see it dripping so at 250 it's it's going a little bit faster now so i'm starting to get into let's say my neptune fuel heavy gasoline is what that is and so you can see it's starting to drip faster and faster and faster at this point my um oh i'm getting closer to 300 degrees is where where i'm at right now uh and so as i got to 300 degrees again we're seeing it going drip drip drip quicker and quicker and quicker so i'm going to say it at 250 degrees we had maybe i don't know three milliliters of gasoline slash naptha on it um when we get to um we're a little bit over 300 degrees right now so at 300 degrees maybe we'll call that five milliliters so we're going to say five milliliters all right 300 degrees i turned up the heat just a little bit but you can see it again dripping more and more and more and so so you know once we get above 300 degrees you know well now we you know start getting into other ranges you know we start maybe collecting a little bit of kerosene here uh we'll keep going a little bit hotter on this and um see how much see how much a light light kerosene or heavy gasoline whatever you want to call it um how much we could actually get now we're at about at uh 375 degrees and i'm right around my uh 10 millimeter mark uh and so you see it dripping pretty quick drip drip drip drip drip drip so 375 it probably would be a good time to switch over so we're going to make the big switch now over it and starting to collect um uh diesel fuel we'll call that so what i got to do is i got to come over here and i gotta get this do a really quick changeover uh do this quick without losing anything ah there we go i don't lose anything at all there we go so now what i'm doing is i'm collecting my diesel fuel so we switched over at three 375 degrees and so you can see that i got about 10 milliliters of gasoline slash nafta there and now we started to collect that we're collecting some diesel fuel here and so we're going to let this boil for a while and see uh how much how much diesel fuel we can get and so i don't need to put the diesel fuel in a cold cold water because again the vapors are heavy enough that they're not gonna they're not gonna vaporize it at a room temperature so we'll set this over to the side and we'll watch this for a while so our thermometer is really close to 450 degrees right now so we'll take a sample at 450 degrees kind of go down and you can take a look at the i don't know if you can see the gases at all in the um in the flask you can see some condensation happening where the thermometer is at you see the bulb of the thermometer in relationship to the tube that's going to the condenser you can see the jack chain in there and again the oil itself in there it's boiling so that oil is a lot hotter than 450 degrees it's just the vapors coming off of it or that's where they're at so if i come over here now and take a look at my my um come take a look at my how much i'm coming out with my condenser so you can see the dripping coming in drop drop drop drop drop drip drip drip drip drip drip hey look at that we're already over 10 milliliters we're actually about at 15 millimeters right now so at 400 degrees we collected about five milliliters of what i'm calling diesel fuel at 450 degrees we select we collected um uh at 10 uh about 10 milliliters a little bit over that but just the very over 10 and see if you look at it we're dripping really good right now drip drip drip drip we're going to get to that 20 milliliter mark pretty soon so so again we're cracking out a good diesel fuel right now right in the range of uh 450 degrees i could have separated out the kerosene if we felt like we needed to but i think that we would have got so so little that um it's easier just to put a little accuracy in the black kerosene went into the gasoline and the heavy kerosene went into the diesel fuel you can see that it's dripping at a pretty good rate right about now okay we're right out about 500 degrees and we collected around uh looks like at least 25 milliliters so far of uh kerosene slash diesel fuel right now uh 450 degrees you know that's in a good range for a diesel fuel at that point in time so at 475 we only had 20 milliliters so we're doing a pretty good job you know we're getting we're getting these five milliliters of fuel for every you know quarter uh you know 25 degrees of increase and so we're going to be hitting 30 milliliters 30 milliliters here before so long but you can see it's dripping dripping at a pretty good rate right now you know drip drip drip drip so again at 500 degrees we're going to call that 25 milliliters okay we're at about 550 degrees as far as temperature and we're right around the 40 millimeter mark for uh collecting our our diesel fuel so you know we're at 550 so we have plenty of room to grow you know we can all be up to 650 as far as a diesel fuel getting into the heavy diesel range so again we're still dripping drip drip drip drip so far we've been heating this uh oil for about 45 minutes you know slowly heating it up just watching it drip to try to collect as much as we can so so we'll keep going until our a little bit further until we get uh tired and decided to collect enough okay we are currently at 575 degrees fahrenheit and we're right around 50 milliliters of diesel fuel collected so that's 25 of our our sample right now is um kerosene slash diesel fuel mix and we still have some more to go so while we're um waiting for this to to go through this uh our students uh that are taking this class um remember that uh page nine of your laboratory manual in the back of your book page nine uh this is a lab one where on page nine there's a sheet for you to fill out in relationship to all the observations that we're making on this particular sample today okay so it looks like we're at around uh 580 or so degrees fahrenheit so we've been boiling this oil for about one hour so that's about what we do in the classroom as far as the amount of time that we have and so one more time we'll take a look at it and you can see that there's condensation going on you know you can see that happening inside the tube and that oil is extremely hot so you know you can see it boiling really good there now it's voting really good i cranked up the heat at the very end here and so it's boiling really really good right now if i come over and you know follow the tube down through the ice bath gotta go slow so you guys don't get dizzy then it's coming down through out of my condenser into my container i could take a look at it and see that i have still some dripping going on and we have right around it'll probably be 65 milliliters before i'm all said and done and so uh that's quite a bit of a diesel fuel out of there it's all said and done you see it's still dripping a little bit i did want to point out one thing for you guys and that is if i move this over a little bit to my previous sample this is what we did last semester and it looks like i got about 20 milliliters of gasoline and i got 45 milliliters of a diesel fuel again and you can compare that to this is the sample that we just did today where i only have ten you know like well why is the difference there why did i only get ten and turn that around there we go and last semester i got 20. well again that's that container is a six month old i opened it up probably a few times so again any of the light ends from room temperature is evaporating plus uh you know we uh we stopped collecting gasoline at 375 degrees maybe on this uh 2020 sample right here we stopped at 400. you know so you know the refinery uh in 2020 wanted to make more gasoline well now scott norman's uh refinery and 2021 wanted to make more diesel fuel and then it's like well why did i collect less diesel fuel over here on this one well again i may have had the temperature too hot and it went up too far we maybe ran out of time you know this is not a very precise measurement that i'm doing here this is just kind of giving examples of students as far as how how how distillation works and how how we could separate the the the different fractions out of crude oil we'll take a sample one more time of our and yeah we got above 65 right now so we're looking at maybe 66 67. i'm gonna turn off the heater and let that thing come up a little bit my guess is when i'm all said and done and i'm probably going to stop it right at 70 probably 70 milliliters at 600 degrees just to have a round easy number to try to calculate students will ask an awful lot that hey i made some gasoline now you know i got 20 milliliters from last semester 10 milliliters from this semester if i save this up can i run this in a modern gasoline engine the answer is no the reason is that this is straight run gasoline and that's before any refining processes before any alcohol ad is added any processes to make this a high octane gasoline so today's engines require a fairly good high octane gasoline you know 87 octane at least straight run gasoline if you're lucky maybe 30 octane it's too explosive uh you start to compress this a little bit and it's going to detonate before the spark plug uh fires and so so we say that the straight run gasoline typically you're not going to be able to run on a modern
