Thanks for sharing, I look forward to seeing the rest of the series.
Thanks man! People like you made me study a university degree on chemical engineering.
Great to hear! :D
Such an awesome video man. I use to do research on catalytic pyrolysis and this video gave me flashbacks to the good old days. If you ever want some of your products analyzed let me know, I run my own analytical lab. Again great video!
Awesome, thank you! That would really help me give some more weight to my work. If you like write me an email and we can talk there. :D

Hazel Chem I am so sorry I didn’t see your response here. I’ll send you an email in just a bit.
Already some results? How about Poly aromatic hydrocarbons and other toxics?
oh god, this is what I dreamed of since my birth, finally!!!
Wow I can’t believe this can be done I’m gonna try this .
Now my thought is to use some of the heat of a reverse flow wood burner (air flow top down through the wood fuel) to heat a separate pyrolysis chamber that breaks down plastic into flammable gasess that is then (after passing through multiple inline copper flame arrestors - for safety) is then fed into the secondary combustion chamber prior to the added forced air. Thus you get the burning efficiency and particulate elimination of the reverse flow with the added fuel value of the plastic (about equal to coal on an energy per weight basis). Reverse flow wood burning is generally a batch process, one load a day.
Top tip - when you have finished the using rockwool, take a COLD shower,. Hot water opens the pores and the itching is worse - don't use as emergency toilet paper - saw a guy do this 40 years ago and it was hilarious
HC - thank’s for your videos - I have a question. Do you have to control the outlet from the reactor to the condenser with some kind of valve, to control the pyrolysis reaction and temperature/pressure or is there a free passage from the reactor to the condenser?
No need it is just some straight pipes. With a valve you would get a pressure buildup which can lead to your system exploding !

Thanks man, I had been looking for the appropriate cooling method. But I have a question, wouldn't it be possible to obtain fuels separately by cooling gaseous fuel at different temperatures as it comes out of the reactor. And using bentonite clay as a catalyst will eliminate the wax produced.
I am not sure about the catalytic properties of bentonite but the first part you mention is possible and I already have a prototype ready.

Great work, looking for distillation analysis of your fractions.
HELL YEAH!!! HAZEL IS SAVING THE WORLD
Hello Hazel, I admire your work and your explanations. Can you publish a list that lists the less environmentally hazardous waste? Would a perlite-gypsum mixture also work as insulation? I used this with my wood gasifier and in this matter it works like a charm - but there it is not directly in contact with the pyrolisis - so this might make a difference?
if the perlite gypsum mixture withstands the similar temperatures it should work. Also thanks for the feedback I will consider it in a upcoming video.

Your voice is beautiful
So basic I can control the composition of the oil by controlling the temperature of the reactor? Are there some guidelines for that, for instance, is there a temperature range that will maximize the production o kerosene, and another range for gasoline?
The video is about a year old, so I'll ask: have you tried using starlight as insulation?... It's a coating that burns to produce a carbon foam that acts as a black body reflector ( if I'm remembering correctly). It may be an easier solution for insulation.
I choose to emit the breathing apparatus. The glue sniffing was great!
youre the man!
find magnesium-calcium silicate insulation ; it has a similar heat-rating, and isn't carcinogenic ; basically the same stuff, -- there's always a mechanical itch associated with insulation, but the silicate is biosoluble.
I feel like we have finally arrived back to the future.
Exellent video. Simply explained. 👍
Thanks! 👍
Very very nice, my friend!!!!!!😊😊😊😊Muito bom, e você é caprichoso!!!Eu convido para compartilharmos, estaremos juntos e mais 💪 forte, Parabéns!!! Muita saude para você e familia!!!!!
yes and in a big freeze it can keep garage warm. stop pipes freezing?
A homade pyrolysis reactor I can turn my garbage into fuel for my car seems like a good investment how much does a project like this cost
you can take fibers out of your arm using the sticky side of tape and rolling it on the itchy spots.
A lint roller works pretty well, too. Not as well as something like packaging tape, but it’s a lot quicker
Tell that to asbestos
Finally, a cure for morgellons
Yeah. Duct tape works great for pulling fiberglass out of your skin
It would be better to wear a slick non-impregnable material such as a PVC rain suit or disposable painting coverall. The fibers will embed into the exterior of woven clothing and then spread everywhere when the clothes are washed and tumble dried.
I would be interested to see what diesel eating bacteria would do with it and if it would be viable to turn put it back into the food chain and eventually carbon sink.
GREAT VIDEO
do you have any plans to upgrade the oil produced through using a catalytic reactor?
Do you know how exactly it works ? İ'd be happy if you could give me some kind of source or a quick explanation.
@Viktor Reznov theres many different types of reactors that you can use and also many catalysts. Some popular reactors are fixed bed, fluidized bed, and spouted bed. Probably the most common catalyst used is a zeolite catalyst called H-ZSM5. Most of the learning I have done has been through research papers that I have access to through my university. If you want to learn more there is a paper called "catalytic pyrolysis of plastic waste: a review" which teaches alot.
@Sean Okonsky thanks a lot. İ don't really know how to find a scientific paper online but i'll type it in and see what comes :)

I appreciate your video,I will watch all your video,I don't have opportunity to study in school,iam poor that's why,my goal in life is Tobe scientist someday,thank you very much
excellent
Dude, I loved it...but since you got that urushibara nickel wanna try a reduction of imines to amines, or oximes to amines
I might give it a try but first I have to hydrogenate the oil :D
mfg hazelChem
Would have obviously like to see you use it
Wow what is your background to sound like you have already accomplished making high grade file!
So good
Can thi system be used for wood seedstock?
Anything organic works, but the materials that don't contain oils will be reduced to raw carbon, which is essentially purified coal. Or you can use it to enrich soil for plants and crops.
Hazel Chem, if using tires to make oil, is there a process for removing the sulphur ?
yes, you have to use molybdenum, cobalt, nickel, as a catalyst and let the crude oil react with hydrogen, the gas afterwards is washed with an amine solution to bind the hydrogendisulfide
@Humbulla93 Thanks for your reply. I'll look through your videos to find that process. This information is hard to find, especially with video of it being demonstrated.
@Mr Stratau that´s true as it´s a very niche process only used in petrochemistry https://www.researchgate.net/publication/266290168_Future_challenges_of_hydrotreating_catalyst_technology here is a bit of the science background, and this link https://link.springer.com/chapter/10.1007/978-3-642-61040-0_1 is a book containing all the informations on this topic a bit expensive though
@Humbulla93 Thanks. I will check it out.
That spray on glue holds up well in that kinda heat?
The glue is only used to hold the pieces during the blanket assembly. Once he coated it with the cement at the last step, the glue is no longer needed and will degrade when it's fired up for the first time.
Seeing as though only ~8% of plastic waste is actually recycled, when do you see a commercial application of this technology being implemented? Could fuel production through pyrolysis ever be competitive economically versus virgin fuel extraction in the near future?
yes i could but not as long as the oil industry is allowed to extract fresh crude oil. (just an opinion do not take this as fact)

what about molten salt?

#question
How to convert pyrolysis oil into different types of oils like petrol , diesel,kerosene, etc. By using distillation. how to make pyrolysis oil distillation small plant
watch my video on the clean up of pyrolysis oil https://www.youtube.com/watch?v=NT4ZneRiL48&t=240s
I might build a small distillation unit but that will need quite some time and money
Im working on a design to incorporate a plastic pyrolysis chamber into the heat zone of a wood gasifier. So every part of the reaction can be used. Not yet sure if it will be possible.
What plans did you use to build the wood gasifier ? Thinking of building one myself
Seems a last coating of kiln wash or the white reflective coating used as the last finish coating in kilns might help a little in better reflecting the heat also. Thanks for sharing. Great build!
Would be neat to augment the heat source with concentrated solar like from a trough or dish maybe something like these designs: https://www.youtube.com/watch?v=0tK3s1Vnol0
https://www.youtube.com/watch?v=xttIZSeEnh8 Not exactly portable however. HHhhmmm.... still and area of opportunity for scaling.
this is better than ASMR and my chemistry class yes
lmaoo pyrolysing the kardashians
Your ceramic fiber is made with asbestos ?
Using a computer generated voice in your (purification of pyrolysis oil) video made it really annoying to watch and I stopped watching it as soon as I head it.
Why the natural voice?? I want computer voice back!!
;)
Great great videos btw!
Hast du Chemie studiert eig?
does this produce car fuel? is it economically viable? I want to assemble one.
yes you can produce diesel, gasoline, kerosene with it , and it is viable as you only need a little propane to heat it up, afterwards when the pyrolysis is producing it´s own gas you can use it to heat the reactor and continue the procedure
Where can I buy one of these units
Currently this is all very experimental, and is a hodgepodge of custom built parts from various sources. Maybe someday in the future a package solution will be possible, once the processes have been more refined and tested.

Hello you all in this video I will explain how you can build your own pyrolysis reactor. The video shows how I am improving my combustion chamber to minimize heat loss. During the video I will answer the most asked questions and give you all the information you need to build your own plastic waste to oil reactor. So lets dive straight into the fun!
To begin you need some spray glue ceramic insulating material and a respirator. As you can see the Insulation in my old chamber is quite thin which decreases the heat efficiency and increases the amount of gas I need to heat the system. Additionally, is the refractory cement coating cracked in several places and needs a work over. To build your combustion chamber in which you will heat your reaction vessel you need a shell. I used some thin steal sheet and bend it into the diameter I needed. But you can use anything if it can handle a temperature of around 100°C. An example for this would be an old metal drum or a big paint can. It all depends on the size of the system you want to build. So now you must loosely attach the insulation material to the wall of your shell I used spray glue for this because it was very easy to do. The respirator is mandatory, so you don´t breath in any glue. You can use other insulation material like stone wool or refractory. An important information is that you should use a insulation material that has a low heat capacity like stone wool or ceramic because the reaction chamber heats ups much quicker and you don´t waste to much energy on heating up your insulation material. A negative example is refractory cement it stores a lot of heat and leads to a long heat up phase and a long cool down and so wastes a lot of energy. But One thing to consider is that the refractory cement is way cheaper and if poured correctly yields a strong and resistant insulation. Insulating the chamber using ceramic fiber or stone wool is very easy. You cut the sheets you have into the right size sprays glue them together and fill up the gaps using the leftovers. For this step it is important that you cut the insulation in a way that you have very big pieces because through every gap heat will escape. To minimize this effect work with a double layer like I am. Alternate the positions where your gaps are in such a way that all gaps have the maximum distance to each over and none of them are on top of each over. This will help you keep the heat in your chamber. When working with ceramic fiber or stone wool you must wear a respirator because fine particles of these materials can lead to irritation and lung damage. Furthermore, I strongly advise you to wear long clothing because after I had finished the insulation my arms were itchy which maybe due to the ceramic fibers that came in contact with my skin.
So now that we have discussed how to build the combustion chamber lets us progress to the second step which is building the reaction chamber. The only material that works good for reaction chamber is metal that should be at least 1.5 millimeters in thickness. You need this wall thickness because the conditions you are putting the reaction chamber in require durability. At the temperature of around 400 to 600°C the reactor is operating metal is already softening and the corrosion rate is drastically increased. So to ensure the safety of the whole system do not use a chamber with less wall thickness.
I used a very large steel pipe and closed one end by welding in a metal plate. After this you need a flange that ensures your system is gastight and doesn´t let of toxic vapor. The best thing to use here is a weld neck flange that gets welded into the other side of the reaction chamber. Just buy the flange size you find fitting for your setup. It is important that you put the flange in a position where no liquid contacts because this allows you to use gas sealing rope instead of very expansive seals. I have used ISOTHERM 800 from the company Frenzelit and it worked quite well. If you want to know how to install the gas sealing watch my first video on the waste to fuel project. When the reaction chamber is completed you need pipes and a condenser. It is very important to note that the pipe coming from the reaction chamber that leads to the condenser has a significant impact on the oil you are producing. All along the connection pipe the vapor will condensate and reflux. Reflux is the term chemist use to describe that a liquid is boiled of and then condenses and drips back into the boiling flask. In this case the boiling flask is our reaction chamber. This reflux leads to more thermal cracking which reduces the amount of liquid oil and increases the amount of gas you are producing. One thing to note is that with more reflux you get a lighter oil which means the hydrocarbon chains are shorter.To put this into simpler terms the longer your connection pipe the shorter your hydrocarbons are. To build the condenser I advise you to go with a simple Liebig type design because it is easy to build and minimizes the risk that your condenser gets blocked. Building a Liebig condenser is easy just weld a smaller pipe into a bigger one. Then connect the inner pipe to a threated pipe so you can connect the condenser to the other pipes in your setup. Drill two holes in the condenser shell and weld on two small pipes where the cooling water hose gets connected. It is hard to give an estimation on how long the condenser should be. I advise you to go with the more is better approach because if the condenser is to short you will get into trouble. So now that we have some basics about the combustion and the reaction chamber let us lock at possible improvements. For this you must prepare some refractory cement and cut fitting pieces out of refractory stone. To prepare the cement you just have to combine the refractory cement and water and mix it well. This is done until the cement has the right consistency. The refractory stone will serve as the base of the reaction chamber because the soft ceramic fiber would be compressed by the weight of the reaction chamber thus decreasing its insulation capacity. The refractory stone pieces must be soaked in water to ensure that the refractory cement hardens in the right rate. When the stones have been soaked, a generous amount of refractory cement is applied, and the pieces are pressed against the wall. This is done until all the refractory stone pieces are in their right place. The trowel is used to fill gaps and scrape of excess cement. This bottom lining with refractory stone increases the efficiency of the whole system but ads a lot of weight to it which can lead to problems in a portable version like mine. So now I want to speak about the process in general and the materials you can and can not use. The so-called pyrolysis is a process in which log chain hydrocarbons are heated in the absence of oxygen.
