Preparation of hierarchical catalysts with the simultaneous generation of microporous zeolite using a template and large mesoporous silica by gel skeletal reinforcement and their reactivity in the catalytic cracking of n-dodecane

Abstract

Hierarchical catalysts with inner ZSM-5 micropores and large outer mesopores in their particles were successfully prepared using a gel skeletal reinforcement method and exhibited superior activity and selectivity for gasoline fraction in the catalytic cracking of n-dodecane.
