OK plastic to liquid. l have some limited experiances with the proces so here it goes.
lt is a supereasy proces anyone can perform.
The basic idea is to heat the long chains molecules of plastic to make them chemicaly unstable, therefore break to shorter chains aka liquid hidrocarbons. The proces starts at about 300c. Temperature plays a role in the lengh of chains produced. Lower temps will produce maynly heavyer products, diesel and wax, but will take longer. Higher temps produce mainly lighter fractions, gasoline and gas, and are fast to achive.
The gas is not favorable as it is hard to collect for later use on a small scale, therefor it is usualy vented or flared off, althugh it is very similar in composition as LPG.
Plastics that can be reformed are PP, PE, PS if i remember right. Unfortunaly PET (bottle plastic) can not be turned to liquid! It forms a cottige chese like product, l suspect this happens becouse of the aromatics in the PET chains.
Catalysts can be used to help the reaction happen, althugh most plastics contain them already (fillers and pigments) and can be seen as ash at the end of the reaction.
The proces is allso quite energy demanding.
As for the fuel produced, l only tested gasoline in a engine, althugh many fractions can be made rangeing from wax to gas. the tests showed great potential but the problem is of its low octane number (under 80) so in a higher compression engine ethanol shuld be added.
As for diesel, it is a high quality fuel with a high cetane number, but it is unapropriet for colder climates as it forms a gel at colder temps.
The gasoline made out of plastic is great for 2t engines (on wich i allso tested it) as it is wery lubricative. I actualy didnt add any 2t oil to it and the engine run nice on it for a long static test, no sigh of wear showed up. This mighs cause problems with injector engines (pligging).
