- hello you all
in this video i am fractionating the pyrolysis oil i have made in my reactor... in a later video we will test the burning properties and see if the fractionated oil can be used as diesel or gasoline
mfg hazelChem - วิทยาศาสตร์และเทคโนโลยี
Ty for make these vídeos, i'm making a pyrolisis plant design and i have learned many things with your videos (somethings i didn't read in PDFs like this), i hope you do more videos in future, ty, i'm from México and i'm university student
Hey! Would you mind sending me your project? I am doing my thesis and it would help a lot
Hola Joel podrías mandarme información? Quiero hacer pirolisis cómo proyecto casero personal
Been looking forward to this for a very long time
I like the words of precaution "Don't kill yourself". Overall, the process is quite intriguing for someone like me who is toying into producing pyrolytic liquids from coconut shells and husk for agriculture applications. Thank you for the clear-cut directions.
Nice to see this process, great job
hello you all
in this video we will fractionally distill the previously made pyrolysis oil
as you can see the crude pyrolysis oil is nearly black in colour and has fine particles supendet in it , and some paraffines formed a small amount of gell at the botom of the char
the distillation we performe is similar to the process used in the petrolindustrie to sperate the different hydrocarbons from each other
therefore we fill the crude oil in a one liter two neck roundbottom flask
at the end of the pouring you can see the solidified paraffines that formed a gell with some of the lighter hydrocarbons splashing in the funnel
to get a better seperation of the hydrocarbons we install a short vigreux collum
this collum works by enhancing the surface on which the gaseous hydrocarbons and the cold glas have contact
the hydrocarbons condens in the collum and release their condensationenergie thus heating up the collum
the so heated collum has a lower temperature than the mixture in the distillation flask, this leads to some reflux, reflux means that a liquid is evaporated and condenst back into the evaporation flask,
on the so heated collum wall some of the hydrocarbons are evaporated again but this time the percentage of lower boiling hydrocarbons is higher then before, this happens all along the collum and sperates the lower boiling from the higher boiling hydrocarbons
presence
the water present is most likely do to insufficient inertisation of the reaction chambers atmosphere which leads to oxygen reacting with hydrocarbons to form water, this in term has to reasons, number one is that i may have used to little carbon dioxide to get rid of remaining oxygen from the air, and the second is that the sealing i am using is not realy made for this purpose and that air could get in the chamber through the ISOTHERM sealing rope
there is a considerable amount of gases dissolved in the pyrolysis oil which can be seen at the adapters of the distilling spider, these gases are driven out of solution during the distillation do to the decreased solubility in hot solution
the second fraction was set from sixty five to eighty five degrees C, so when the temperature needed was reached the collection flask was switched again, as you can see the way i am doing it is complicated and labour intensive, if i had had the right equipment the change of colection flasks would be just a matter of twisting the spider ninetee degrees
the second fraction is a lot more cloudy and has a yellow colour to it which shows us that the composition of the two fractions we already collected differs quite a lot
the third fraction from eighty five to ninety five degrees celcius has to separate phases, with a upper hydrocarbon and a lower water layer
at around one hundret and sixty degrees decomposition reactions occur in the distillation flask indicating that the non heat treeded pyrolysis oil is not stable
the distillation was stopped when the decomposition occured and the flask was swapped again to save the third fraction
here you can see the different fractions and how they vary from each other in water contend and colour, all of these fractions were dryed by first separating the organic and the water layer and then stirring the organic phase with tenn cubic centimeters of three angström molecular sieves
to yield nice and clear hydrocarbon fractions which will be shown in a later video, here are all the datas i collected about these fractions
the distillation residue was transfered into a storage vessel and will be processed later
have fun and do not kill your self
@Hazel, only if i don't see the end of this video🤣, because I'm planning on a project on how to make roof tiles and pavements from waste plastic and sand. With this a channel can be upper as to have a lower temperature for not over melting the plastics
Hello Hazel. Where does one get the angström molecular sieves from please?
You are get oxygen from the No1 (PET) plastic you are putting into the chamber. Don't use PET and PVC plastic.
@@markdixon2825 hello mark i only now saw your comment ..... you can buy them from resatauro and many other sources online
mfg hazelChem
After purification we use this fuel on car and bikes ?
Very interesting,please continue for next video
SUBBED.
I am really excited after finding this channel.
I am only 2 vids in and they were both awesome.
nice to hear that you like my videos thanks ^^

I have a gut sense that you could obtain hydrocarbure in a fairly small range of combustion points if you control the output of the boiling chamber.
I am thinking you could use a spring pressed kind of lid that would prevent the gas from exiting the boiling chamber until a certain pressure is present.
If the source of heat is constant, I think this will also translate in a fairly small range of HC chain lengths that reach the condensation phase.
Keep that pressure up until everything is burned, then leave the gas flow freely, driving the condensed fluid somewhere separately.
The small amount that is condensed last and is not regulated by pressure can be used in the next batch.
Nice teaching from the previous one till now. Still enjoying every bit. Because it baffles me more to see a lady showcasing such demonstration.
the only reason i have the lady voice is as a tribute to chemplayer (a now deleted channel)
mfg hazelChem
For a little makeshift setup, do you think the yield would be affected if the reflux column and Liebig condenser were made from copper or stainless steel? I would think as long as there isn’t any sulfuric or hydrochloric acid byproducts it would be fine. PVC and other compounds containing chlorine would need further treatment before coming in contact with the stainless (and to prevent chlorine gas production).
That said, will a stainless or copper condenser work?
For reflux, if you dont have that special glass bottle neck attachment, you can use a metal chain
I am curious. Who made your glassware. I’ve seen some on Amazon, but always curious is there are stand out makers.
Would these fractions from this boiling point be the most equivalent to gasoline used for small motors?
Please continue!
Thank You Very Much for Making such Informative Videos, I'm Mechanical Engineering Final Year Student and Making my Project on pyrolysis.
Your Videos are really helpful to me.
🙌
Can you send your contact number please
So are you converting plastic petrol to a form of gasoline? What kind of kit do I need to order in order to do the same thing myself?
I love the concept of using trash to make fuel!!!!!
You are right those people must understand when making these tips of videos you must be acuity when demonstrated and must be vary thrall an communicated the process
Is there a parts list to help us make our own? This video is awesome!
Nice information
Why did you use 3 A MS instead of just cheap Na2SO4 with filtration?
If you can make a cut that is oily but not thinner than diesel you have a solid alternative fuel for diesel engines. Thicker than diesel and thinner than clean veggie oil and you should be good, so long as the flash point is not to low.
Hello sir, I am just wondering about one thing, first of all, we heat the plastic and form the oil.
And then you heat the oil separately and create gasoline and diesel fuel?
Great
I love the engineering and the chemistry knowledge that went into this but very impractical to average person to do.
I think this is more so a testbed for developing for community scale recycling like Precious Plastic. Too hard for 1 household, but for a community center/makerspace it is easily do-able.
Also good as a learning tool for students.
@@ericlotze7724 👍
Maybe impractical for a person like you. But trust me, If you’re willing to get your hands dirty, this is a very practical process with TONS of potential. We should have been doing this a long time ago.
@@johnsanchez8029 That must be it
Essentially what you have is a crude oil so is it possible for this oil to be shipped to a oil refinery for purrification and if so is it possible to industrialize this process
Big oil would have anyone’s head on a pike who tried tho, lol
What happens if you add hho or steam into the reaction?
If we have to do the work of making diesel from plastic, then which certificates are needed for this?
Have an insulated cap on top to get a better fraction with also less heat.
I would have been interested in an analysis of the products
A lot of the problem here is getting laymen to understand the process. If someone knowledgeable were to give classes in this to people, for instance farmers then you would be able to get them schooled well enough to start either building these machines or perhaps to simply buy one already built. Getting peoples hands on the equipment under trained supervision so they could understand how it all works would go a long way to getting this from the lab to the field. But you have to be willing to work with that human factor otherwise stuff like this is just fodder for someones stash of old USB drives gathering dust in a drawer or a few people with the skill to build such a system. It is an idea worth pursuing for sure , if a farmer or who ever else could just go out picking up plastic when he wanted to fill his gas tank that would be a very good thing for all of us.
gonna build it for sure
hi we make the same experiment but the issue, after distillation the color change back to dark red can you please clarify
How did you check chloride levels please..?
What did you out in at 1:15
???????
What catalytic agent can I use to remove sulphur, or to make the fuel stable and ready to use in car. Is plastic oil good for cars?
Charcoal
If I remember what I've read, natural zeolite has been used as a catalyst to remove sulphur. The fuel still was mixed with diesel at no more than 10% to get the same efficiency as straight diesel. The document stated it would work as bunker fuel in cargo ships or generators without being cut.
molybdenum, nickel, and cobalt sulfides, if it´s cleaned up properly there´s no problem, as it´s chemically the same, if you have an old tractor you can just pour the pyrolysis oil directly into the tank
@@Humbulla93 can you explain the method of using the material
@@mohamedelnadi6232 those sulfides are imbedded in ceramics and are finely spread out to increase surface area thus increasing the efficiency. here is a bit more information on the process www.imoa.info/molybdenum-uses/molybdenum-chemistry-uses/catalysts.php
From wich kind of plastic could someone make it?
hello, i'm going to assume you're german because of the "mfg" at the end of your comments lol. assuming you live in germany/austria/switzerland (which i think are all equally as restrictive when it comes to reagents and lab glassware), where did you buy all your equipment from? i live in germany and can't seem to find glassware and some specific reagents easily (or they are way too expensive). thanks in advance!
well just register in a chemistry forum there is a lot of trade that should allow you to get the things you need cheaper than just buying them online :D
mfg hazelChem
@@HazelChem i see, thank you!
Ebay -> Deschem
do you have the composition run on Gas Chromatography to find the separate component of each distillate?, kindly reply please, thank you,
not yet maybe in the next months
mfg hazelChem
@@HazelChem looking forward your Gas Chromatography details, thank you,
A gas escapes during the heating(?), it does not seem to condense? Is it flammable? If so do you have a guess of its composition? ( I assume the water condenses out in the water cooled condenser, yes?)
It is probably short chained hydrocarbons because it was flammable.
mfg hazelChem
So we can use it to our vehicles now??!!
i pyrolyzed PS, i made small reactor (30 lts) , is any way to eliminate the odor of the pyrolytic oil? what consideration i have to take care to Distill this pyrolytic oil to fuel (gasoline and diesel), what about the Contaminant. do your think with only the distillation the result fuel coul be used in engine?
if have tried many things but i could nor get rid of the odor. Polystyrene oil is not very well suited for engines because the main product is styrene which polymerizes back into polystyrene which will destroy your engine! the PS oil would work if hydrogenated.

Lye and water
Can I get the Journal?
Haha great advice 👍 have fun please do not kill yourself
which is petrol and diesel ?
Thank you for such experiment. I wanted to perform this on my own to analyse that fractions but I don't have the Chemistry knowledge as good as yours. Are you thinking of making experimental unit which will be pointed to make profits? If yes please let me know I'm open to cooperation. I'm from Poland.
profit from diesel or petrol or anything....
it is more of a self sufficient thing than a profit thing... but the unit will be upgraded soon to make it much more energy efficient :D
mfg hazelChem
well depending on the energy source you are using you can sell the crude oil with profit or fractionate it and sell the naphta
mfg hazelChem
@@HazelChem i have a pyrolysis oil from biomass but i wish to do the engine test. How can i do distillation done. Please help me in my work
What about to put a water pump to pump this oil in the reaction chamber until you distillate the pure fuel with the pyrolisis reactor distiller?
doesn't work like this there is no such thing as pure fuel ! the fuel is a blend of specific fractions
mfg hazelChem
Good experiment. Unsaturated hydrocarbon are of course present, these can polymerize in air and become tar and low your hydrocarbon yield. You should add some radical scavenger in the crude pyrolisate, just after recovering. Few milligrams are enough.
hydroquinone for example should work.... i will try this with a sample the next time! for your catalyst idea i don´t see how (without stirring) sand silica will help in this process... in sveral papers i read all come to the conclusion that there are nearly no beneficial effects of a catalyst
mfg hazelChem
@@HazelChem No. Catalyst help a lot in cracking. For example calcium oxide is fundamental for PET pyrolisis to yield benzene as major fraction.
@@zodd0001 could you send me links or names for the papers you are referring to?
mfg hazelChem
@@HazelChem Yes. This is one. Look also on google patent digitazing " pyrolysis ":
pubs.acs.org/doi/10.1021/acssuschemeng.6b00450
So for the laymen out there, what is the end result of the liquids from the different temperatures? Like is one diesel, regular then premium? Etc?
Yes
Thanks my friends
Pyrolysis oil is Good or Bad?
I want to know answer of this question. Because,i'm going to start tyre/plastic to oil pyrolysis.
pyrolysis oil can be described as "good" .... but there is a difference to tire oil !!! in tires is sulfur which forms sulfur-hydrocarbons which when burned release sulfuroxides ..... and they are very harmful to the environment !! so unless you have a catalytic desulfuring plant please do not pyrolyse tires
mfg hazelChem
Hello: I congratulate you, I really like what you are doing. The product you get is a um blend of hydrocarbons. It is appreciated that it is not stable, possibly there was oxidation reaction, because it is cloudy. Will it be a solution to use any antioxidant agent? have you tried it ?
the instability comes from the PS and the formed styrene the double bonding has to be eliminated to create a stable fuel
mfg hazelChem
What solution do you have to create a stable fuel@@HazelChem
@@HazelChem what agents should be used to create a stable fuel?
Could i make a stainless steel version of this and somewhat simplified?
yes this is possible maybe i will weld one when i have time
mfg hazelChem
@@HazelChem I am going to open source mine, but i need to make a secondary man portable unit to distill it further. I have something ready to test tomorrow. Next stage was to make the SS version, or copper fittings from hardware store for the secondary purification. Maybe solar power option. www.minds.com/pacstove/
So are you telling me that through fractionally distilling crude pyrolysis oil you can not only produce fuel, but also liquid water? Is this water safe and can it be separated, collected, and stored for consumption or other human use?
Water only created as a byproduct of the heating of atmospheric oxygen coming into contact with the hydrogen atoms attached to the plastics hydrocarbon structure. Not really practical to try and collect it because of how little is actually formed. Especially if the build is air leak proof and no CO2 is used in any stage at all, the likelihood of water formation on the product side of reaction will hardly exist.
Someone please correct me if I am wrong here. But I am pretty sure that’s the case.
Much love to all of my fellow chemists and physicists out there that are doing great things with their knowledge.
More people need to study science and math instead of law and business. No great empire of the past has ever lasted. And when democracy fails and oil production screeches to a halt, all of your business and law degrees will only be good for wiping your asses with. Take advantage of this free knowledge while you can because sooner than later, we will experience an oil crises and things will never be this way again. They addicted us to energy and it f**ked us real good in doing so.
Dear Sir at what vaccum pressure it will be fully distile
Same question.
I wan't to Vacuum Distillate the TYRE PYROLYSIS OIL, but unsure whether what Vacuum pressure must be maintained😕
Can we please talk.i am really into recycling of wastes.i am a mechanical engineer from india.
Is that a bong
at what temperatures do we get gasoline?
how about temperatures for diesel?
depends .... and you still have to blend the distillate with the right amount of additives
mfg hazelChem
Hazel Chem can you specify the temperature for gasoline and for diesel?
GREAT VIDEO. Curious what chemicals are in each fraction
Good question! When this pandemic is over and my university is open again I am allowed to do some analysis in my campus.
mfg hazelChem
@@HazelChem
First flask t
Is there any danger of explosions while you're doing this?
Hardly. The self combustion temperature of all hydrocarbons in that mixture is way beyond the temperatures involved in this process.
I had a thought. Maybe a dumb thought as Im definitely no chemist. However what if you put some Alum in the dirty oil. It should separate . Pour off clean, mix with alcohol .
that´s a idea but not a practical one you need to distill it anyways so that you can blend the different fractions so you get a fuel that meets the standard
mfg hazelChem
@@HazelChem meeting what standards, and if you meet those standards then it means your fuel can be used in normal cars?
What do you do with the rest leftovers arter the end of the whole process?
kill it with fire XD ... no but seriously burn it so most of the toxic hydrocarbons get harmless
mfg hazelChem
Hit it with a caustic like red devil,
It will separate the oils into different weights
Can you do an amazon link in the description
what do you mean ?
@@HazelChem I believe he wants to know where he ca acquire the glassware and burners to do this experiment at home.

How do you remove sulfur content ?
By not putting anything containing sulfur in the reactor.

Hi, thanks for the video, can you try to distill waste engine oil into diesel
Hi Miguel
I am currently doing running that project with a self made distillation column.
Pardon me I meant to say "running"
@@zarakirai wow. Thats nice and what end products you making? Are you from South Africa.
short answer, chemically yes, financially, depends on oil quality and cost.
Bonus fact. Nazi Germany Does not have oil fields, neither one of the occupied countries, yet it managed to mobilized large army, via coal conversion into synthetic fuel.
@@sh3junior thank you and I get the sense of German nazi...
Based on the temperature used, you get a kind or another of fuel... Ok, but what kind of fuels are they? Is there a way to chech them to see what they are?
They are hydrocarbons. If you want to check after fractioning, you might be able to get a general idea by measuring the refractive index.
How to contact you . I have some business proposal as a start up
hazelchemistry@gmail.com
A business proposition from a random TH-cam user.. seems legit...
that is one crazy looking bong
Time to grow up.
Nice ideal...could you please tell me how to remove sulfur from diesel?
Its is removed by hydrodesulfurization which is complex and it require high temperature and pressure so only industries can do it

The biooil is very unstable it is the main reason why this tech hasn't gone anywhere . try mixing a solvent like methanol or similar and vacuum distilled in 1 vol oil to 4 parts solvent. I have a huge amount of info on this if you need it.
Hi
Please I need this info
I can't tell you how bad all of that stinks.
Dangerous. Kids you need your parent consent before doing this. In case you burn down your dads garage.
hahahahah..... well i laughed there ;D but thanks for the advice
mfg hazelChem
when you though you knew how to English:
Take this automatic speech away , I'm leaving now
So stupid. The thought of widespread DIY'ers burning plastic to make fuel is a horrific nightmare. Even in highly controlled labs the recapture of toxic gas and byproducts such as waste ash, are challenging. Fudging the clean-claims and success rates is middle of the road in this corrupt idea in innovation.
The disguised voice seems to indicate that the makers want to distance themselves from personal accountability for their dangerous experiment. irresponsible, toxic solution.
Really nice to keep toluene and other flammable substances near to heated bad. "Don't kill yourself!"
Thanks for the comment. Storage in Schott Bottles is considered to be save for higher boiling hydrocarbons like toluene. But i have updated my safety standards in the lab.
the do not kill yourself is an inside joke between me and my friends ^^
