Synthesis and characterization of zeolitic composite ZSM-5/MOR with multi-modal pores

Abstract ZSM-5/MOR zeolitic composite was prepared by a two-step synthetic route and characterized by SEM, N 2 adsorption and NH 3 -TPD. The results showed the composite has different acid property and multi-modal pore structure from the physical mixture of two zeolites, and a strong acid center is formed in the composite. In the catalytic cracking reaction of n-octane, the composite ZSM-5/MOR has higher conversion and longer life than their physical mixture.
