What are the product yields from pyrolysis?
Product yield is related directly to the type of plastic feedstock used, the reactor type and the process conditions, particularly pyrolysis temperature. Through the use of low-temperature pyrolysis and efficient cracking, liquid fuel yields of up to 8085% are possible, with the resultant product resembling diesel fuel, kerosene, gasoline or other useful hydrocarbon liquids. An added advantage of pyrolysis is that the light product gases (LPG and gasoline) produced (additionally to diesel) can be used to provide the energy requirements for the process. The product yield depends on the distinction drawn between Mixed oil (Burnable industry fuel) (also called ‘agricultural diesel’) and Refined transportation diesel (which meets the EN590 specification). The liquid fuel yield (that consists of both diesel and petrol) is 80-85% while the yield for the refined transportation diesel (the gasoline fraction has been extracted) is 40-55%.
