CATALYST FOR DEGRADATION WASTE-POLYMERS INTO THE MIXTURE OF LOWER HYDROCARBONS AND A METHOD OF DEGRADATION WASTE-POLYMERS INTO THE MIXTURE OF LOWER HYDROCARBONS USING THE CATALYST

摘要

The present invention provides a zeolite catalyst for converting waste polymer materials such as polyethylene into low molecular hydrocarbon mixtures that can be used as liquid fuels of gasoline to diesel grade in a liquid catalytic cracking process, and a method for converting waste molecular materials into low molecular hydrocarbon mixtures using the same. To provide. The zeolite catalyst added to the process of converting the waste polymer material of the present invention into a low molecular liquid hydrocarbon mixture was prepared by controlling the molar ratio and particle size of Si / Al to increase the yield of the liquid product and control the degree of decomposition. The present invention provides a method for improving the yield of a low molecular weight hydrocarbon mixture and quality as a fuel by controlling the external surface properties in order to suppress the deactivation of the catalyst.;[Index] Decomposition of Waste Polymers, Zeolite Catalyst, Liquid Phase Catalysis
