Pyrolysis of Plastic Materials, Using for Manufacturing of Components of Car’s Fuel Feeding System

Abstract

One from aspects of urgent problem of minor details’ replacement in cars on plastics details is connected with reclamation of worn components. At present, in motor vehicle industry is actively put into service high density polyethylene. The main method of reclamation of plastic materials, and polyethylene, particularly, is high temperature pyrolysis. The works on targeted research of composition of polyethylene pyrolysis products related to the middle of last century, and level of technique of that time didn’t allow to authors in depth establish this composition. In this regard is of concern research of composition of volatile fraction of polyethylene’s pyrolysis products with the application of modern research and analytical equipment.  There was conducted pyrolysis of high density polyethylene with application of two-stage pyrolyzer with analyzer of composition of volatile hydrocarbon fraction by means of method of chromatography-mass-spectrometry, and obtained data on pyrolysis’ kinetics with the aid of thermoghraphic analysis. As a result of pyrolysis is received qualitative fuel (normal alkanes C2-C6 and benzene). High-boiling fraction, consisting from the mixture of olefins and dienes C18- C20, is suited as additive to motor oils (technology of Mobil Oil). The single solid product of pyrolysis is soot.
