摘要：

Rhenium-impregnated HZSM-5 is found to be a promising catalyst for ethane aromatization. The Re-HZSM-5 catalyst deactivates significantly slower than well-known ethane aromatization Zn-HZSM-5 catalyst. Product selectivities for the two catalysts are similar, indicating that the shape selectivity and acid-function of the zeolite are the determining factors, and the metal function is only responsible for the activation of ethane by dehydrogenation to ethylene.
