Chemical Recycling of Waste Plastics: Catalytic Cracking of Heavy Oil from Waste Plastics over Ni-Rey Zeolite

Abstract

The increasing amount of waste plastics which causes serious pollution problems is a cheap and abundant source of chemicals and energy. Chemical recycling method which recovers hydrocarbons is recognized as the ideal approach in recycling the waste.1 The economics and engineering constraints in the chemical method of a combined pyrolysis-reforming reactor has been discussed earlier.2 The pyrolysis-reforming reactor was found to inhibit systematic study on the effects of various reaction conditions. A proposed process scheme of independently studying the pyrolysis and catalytic reforming reactions has been shown to alleviate the constraints of the combined pyrolysis-reforming scheme.2
