EFFECT OF POLYOLEFINS ON THE PYROLYSIS OF BROMINE AND CHLORINE CONTAINING MIXED WASTE PLASTICS FOR PRODUCTIONOF HALOGEN FREE LIQUID PRODUCTS

摘要

The pyrolysis of non-halogenated polyolefms for the production of chemical feedstock/fuels is well known process today. However, the pyrolysis of polyolefins mixed with the halogenated (chlorinated and brominated) plastics produces the various halogenated (organic and inorganic) hydrocarbons in pyrolysis products and removal of such halogen compounds is possible by use of suitable catalysts/sorbents. The pyrolysis of polyvinyl chloride and high impact polystyrene with brominated flame retardant mixed plastics were studied and we showed that the utilization of catalysts/sorbents can be minimized or avoided by selection of suitable process conditions and parameters.
