Catalytic Cracking of LLDPE over MCM-48
Applicability of Al-MCM-48 as a catalyst for the linear low density polyethylene (LLDPE) degradation was investigated using a thermogravimetric analyzer as well as a batch reactor. The degradation products were analyzed by GC/MS, GC-TCD and GC-FID. The activation energy of LLDPE degradation was lowered by the addition of Al-MCM-48. The oil and gas yields were higher over Al-MCM-48 than those over Si-MCM-48. Al-MCM-48 generated mainly C7-C10 hydrocarbons, while Si-MCM-48 exhibited the relatively broader distribution of the oil products (C8-C14). Al-MCM-48 showed high catalytic stability for the LLDPE degradation.
