Abstract

Catalytic degradation of polymers over catalysts has the potential to recover valuable hydrocarbons from waste materials. Polymers were pyrolysed over different catalysts using a specially developed laboratory fluidised bed reactor operating isothermally under ambient pressure. The yield of volatile hydrocarbons (based on the feed) was typically zeolites (HZSM-5 > HUSY = HMOR) > Silica-alumina (SAHA) »silicalite (Si/Al >1000).Product streams varied markedly dependent on catalysts type and structure. Greater product selectivity was observed with HZSM-5 and HMOR as catalysts with over 80% of the product in the Cj-Cs range. Both MOR and USY produced more paraffinic streams with large amounts of 4. A kinetic model based on a single irreversible reaction scheme for the observed products has been developed. The model gave a good representation of experiment results, and aided understanding of the influences of polymer feed and catalyst used. Copyright ©1999 by Kodansha Ltd.
