Hey guys,

I know that this is mainly a forum about chromotography, but maybe someone from the industry knows enough about polymer pyrolysis to give a hint.

Our company is trying to pyrolize polymer waste into diesel fuel, but so far they are mainly getting wax product, and cannot do anything with it.

The pyrolysis is thermal, done at ~450 degrees C, and uses Fly Ash as a catalyst.

Before they work at the factory we usually run a lab pilot of the waste, and usually we get better results than in the field (As expected), but we still get a lot of wax product.

Is there anything we can do to swing the reaction in the direction of liquid hydrocarbons? (I've read that there are some methods that catalyse the reaction all the way to syngas, but that's undesirable for us)

Thanks in advance.
