Catalytic polymer degradation for producing hydrocarbons over zeolites

摘要

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 pressure.The yield of volatile hydrocarbons (based on the feed) was typically zeolites (HZSM-5>HUSY approx approx HMOR) > Silica-alumina (SAHA) ailicalite (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
