摘要

Alkali-treatment and Fe-Ti-loading were used to modify ZSM-5 zeolite. It was found that alkali-treatment created mesopore and Fe-Ti-loading improved the redox property of ZSM-5 catalyst, although both modifications led to a reduction of the total acid sites amount. The catalytic performance test indicated that the coexistence of meso-microporosity and Fe-Ti-loading on ZSM-5 catalyst is benefit to improve the yield of light olefins in catalytic cracking. The catalyst containing the combined modified ZSM-5 increased the propylene yield by 0.55 wt% and total light olefins yield by 0.69 wt% in catalytic cracking of Canadian LGO (light gas oil), compared with the reference HZSM-5.
