Özet

The catalytic thermal degradation of polypropylene over aluminum containing ordered mesoporous MCM-41 and SBA-15 based materials was studied in a semi-batch reactor. Heavier molecules degraded to lighter hydrocarbons in the presence of catalysts and they gave high ethylene selectivity among the gaseous products. Additionally, butane selectivity increased with the use of catalysts. SBA-type catalysts showed higher selectivity to lighter hydrocarbons (
