What could these chemicals be?

This person claims plastic pyrolysis oil improvement

What is the chemical in the video?

thks Wheels!
But i am refering to PET PLASTIC. as used in coke bottles?

soot and smoke problem

Hello to everyone
What can I do to chemically purify tyre pyrolysis oil
I need to use it as a diesel in the generator. I filtered it with simple bleaching earth. There is too much smoke. There is too much soot. What can I do to reduce soot?

Can some one remind me why we can't use PET in our process.I know we discussed before, but it seems the Chinese are doing it?

Hello to everyone
I want to use pyrolytic oil from waste tires to generator.
I think this oil distillation. Is it enough to heat up to 300 degrees and distill?
How much product do I get?
Have you tried this?

It can be done, but the Fuel you get from Tires is very black and it smells.
About 50% of a Tire is made up of Carbon Black. So after the Fuel is removed, you end up with a lot of Carbon to get rid of. If you process whole tires, then you will also have a lot of steel wire and some Tires have Kevlar in them, which does not melt. So you end up with a lot of rubbish to remove.

If you are referring to the high impact plastic used for all electrical appliances, simple answer is no.
The plastic is called ABS. This is the stuff I play with. It contains many nasty chemicals used as fire retardants. The most common being Bromine. Bromine is a Halogen. ABS is also full of fillers to make the plastic hard or soft. Mainly clay is used and up to as much as 50% of the plastic can be clay.
The fuel that comes off Ethyl Benzene(styrene) which stinks and is more related to Petrol than Diesel.
To make is simple, Stay away from ABS (or HIPS).
Another plastic to stay away from is PVC. This is found as electrical insulation among other things. This plastic produces as much as 50% of it's weight in HCL. It is very dangerous.

Thank you, for the info.

thanks WHEELS ...as i read pp and pe is much better..so if i remove all papers and wash all plastic well does not produce h2s and hcl? thanks

Is HIPS (hi impact polystyrene) user friendly in our pyrolysis systems?
When making diesel from WMO, are you folks centrifuging or using seperators to take out the fine carbon particles before using in your vechiles?

EXCALIBUR i mean i read posts but some poeple say that pp and pe doesnt produce h2s and hcl and others is saying that it is imposiple..

I have been busy and have not had time to check in. It's good to see some posts again.
Jonathan, I suggest you use a bubbler. It is the easiest thing to do and will eliminate many different issues for you.

Flame will indeed travel through a small gap. Don't get fooled on that one. There are three key points to having a fame. Fuel, Heat and Oxygen. Take one of those three away and you do not have a flame (combustion). What fine mesh or lathe swarf effectively does is to remove heat. It wicks away so much heat so quickly that a flame cannot be supported. Providing the heat of the swarf is held below the flash point of the fuel. Which brings me to the next point. Because there should be no oxygen present, there should be no combustion either. Using a bubbler does isolate any possible combustion, but it also aids in providing a cold means of condensing the gasses quickly and the result is that the gasses that may escape into the air will condense and float on the water surface to be collected.
Does waste oil produce acid?? Yes it can. It depends on what is in the waste oil. A Petrol engine produces acid when it operates. For every 10ltrs of fuel burned, 1 ltr is water vapor (ruffly, because it depends on air humidity) and 1 tenth of a ltr is Sulphuric acid (ruffly, because it depends on fuel quality). That acid seeps down into the engine oil and is then changed out when the engine has an oil change. There can be many things in waste oil. Like solvents and other cleaners a mechanic may have used and discarded. So unless you know 100% the quality of the WMO, you do need to take great caution in the gasses that come off during processing.

It might help to post those opinions here...

thanks excalibur but many opinions and now i am confused

[Excalibur]

i read that wmo pyrolysis produce h2s and hcl gases.so if i use water bubbler it is good for hcl? and h2s as i read it can be burned. and my other question is about plastic pyrolysis..if i use only ps.pe.hdpe and ldpe are they safe? i mean no danger gases like hcn hcl and other? because i find this post says:...Toxic by-products of pyrolysis of polystyrene (PS)
Since polystyrene is not a halogenated hydrocarbon, then the by-products of pyrolysis are going to be just petroleum vapors, which are toxic, and flammable; however, they can be effectively handled with simple condensation via a succession of air, water and ice cooled condensers. Any non-condensable hydrocarbon can be burned in a flue gas controlled burner.thanks

As I recall, there was good talk about these very topics earlier in the forum. Researching there would be a good start.
