Olefin Rich Fractions for Polymer Additive Synthesis Obtained from Waste Materials (RDF and MPW)

摘要

This paper focused on the thermal and thermo-catalytic pyrolysis of refuse derived fuels (RDF) and municipal plastic wastes (MPW) in a batch reactor at 450°C. Two commercialized zeolite catalysts were used in order to enhance the quality of the feedstocks petrochemical productions (e.g. olefin rich pyrolytic oils). Analyses of products were carried out using GC, FTIR, EDXRFS and SEC. It was discovered that the presence of catalysts in the processes have a considerable effect not only on the quantity of product yields but also to the product compositions. X-ray analysis had demonstrated significant contaminant levels in each product obtained from only RDF pyrolysis. Characterization of pyrolytic oils indicated the existence of hydrocarbons between C5 and C_(29), with different structures (isomers). New routes for the utilization of products obtained by waste plastic pyrolysis have been investigated, α-olefin-succinic-anhydride intermediate based additives have been developed and tested in polymer blends.
