Effect of Fe Loading Content on Catalytic Performance of ZSM-5 for the IMTO Process

Abstract:

Among the processes for production of olefins, methanol converted to light olefins with methyl iodide as intermediate is a potential and an alternative route, which can be realized under mild condition. ZSM-5 catalyst is considered to be an effective catalyst for methanol to light olefins, better performances for olefins can be obtained by modifying. In this paper, the methanol to olefin with iodide reaction (IMTO) has been studied in a small scale fixed bed reactor over Fe modified ZSM-5 catalyst. It is indicated that ZSM-5 zeolites were modified with Fe loadings successfully, as a result the pore sizes reduced availably comparing with ZSM-5, the conversion of methanol and selectivity of light olefins got 98.8% and 89.5% respectively when modified with 9% Fe loadings.
