摘要

Abstract

Waste plastics mainly come from MSW and usually exist in the form of mixed plastics. During the co-pyrolysis process of mixed plastics

various plastic components have different physicochemical properties and reaction mechanisms. Considering the high viscosity and low thermal conductivity of molten plastics

a falling film pyrolysis reactor was selected to explore the rapid co-pyrolysis process of typical plastic components (PP

PE and PS). The oil and gas yields and the compositions of pyrolysis products of the three components under different ratios at pyrolysis temperatures were analyzed to explore the co-pyrolysis characteristics of PP

and PS. The study is of great significance to the recycling of waste plastics.
