RESEARCH PAPERS : PYROLYSIS OF PLASTIC WASTES USING THE NON-CATALYTIC HAMBURG-PROCESS AND A CATALYTIC PROCESS USING THE CYCLED-SPHERES-REACTOR

Abstract

Mixed waste plastics from the DSD (Duales System Deutschland) were degraded by the Hamburg-Process using a fluidized-bed. The experiments purposed to obtain oils and heat-providing gas. Experimental results from the laboratory-scale- and pilot-scale- Hamburg Process were compared and analyzed. The most important products were BTX and styrene. On the other hand, a commercially available sample of polyethylene was decomposed over zeolites in the cycled-spheres-reactor. In the experiments, Y-type zeolites showed lower activity and higher deactivation than H-ZSM-5. H-ZSM-5 and Y-type zeolite of higher module showed less deactivation, but lower activity than those of lower module.
