摘要

BACKGROUNDZSM-5 zeolite has been used as a common support for PtSn-based catalyst in the propane dehydrogenation reaction. But owing to its high acidy, coke accommodation and stability of the catalyst are not satisfactory. Here, in order to improve the performance, the new hierarchical-porous ZSM-5 (abbreviated henceforth as ZQ) has been synthesized.
