The theory of tire pyrolysis machinery is through pyrolysis, let solid tire become oil gas under high temperature, then by recycling water, cooling down oil gas to liquid oil. So during this process, no need to use catalyst. However, distillation machine need catalyst, since we want to change tire or plastic oil into diesel, so we must use catalyst to reflect with oil, regarding to the name of catalyst, i am really sorry that i can not tell you now, but it exists in all market, and per ton oil need about USD10 catalyst.
