Characteristics of a new type continuous two-stage pyrolysis of waste polyethylene

Waste polyethylene (PE) was pyrolyzed in a continuous two-stage pyrolysis process having auger and fluidized bed reactors. The main aim of the study was to produce a pyrolysis gas containing high contents of olefins along with a clean pyrolysis oil at moderate reaction conditions. In the experiment, the temperatures of the auger and fluidized bed reactors were varied from 30 to 300 °C and from 653 to 736 °C, and a CaO hot filter was used to...
