Description

The effect of the organic species in the synthetic gel of ZSM-5 on the distrib ution of Al atoms in the MFI framework and catalytic performance were invest igated; ZSM-5 zeolites were synthesized by exclusively using TPAOH, and Na cations with PET to elucidate how the distribution of Al atoms is governed by the types of organic species in the synthetic gel. The distribution of Al atoms was investigated by 27Al MAS NMR technique and constrain index (CI). The re sults obtained in catalytic cracking of 1-octene over the ZSM-5 catalysts revealed that the fine-control of Al distribution in the MFI structure could improve the tolerance for coke deposition in 1-octene cracking.
