大分子正十六烷的催化裂化
Catalytic Cracking of n-Hexadecane
摘要
Abstract
A new kind of hierarchical ZSM-5 zeolite catalyst with hollow and thin shell structure was synthesized and tested by cracking of n-hexadecane to study its pore effect and acid properties.The results showed that this zeolite catalyst had better catalysis activity and prolonged life because of its improved molecular diffusion brought by its mesopores and macropores.In addition, large amount of acid sites on the hierarchical pores can be more beneficial to large molecular reactions and get better product selectivity.This structure-activity relationship is more obvious especially on short contact time conditions.In a word, catalysts with proper activity distribution as well as hierarchical pores, hollow and thin shell structure should have better activity, product selectivity and prolonged life, which can provide the basis to design novel high-performance catalysts in the future.关键词
