摘要：

The conversion of ethane into aromatic compounds at 550 degrees C and atmospheric pressure over Zn-ZSM-11 zeolite (Si/Al=17; 2.5 wt.% of Zn as counter ion) has been studied in a now reactor at different partial pressures of ethane. The observed products at different ethane conversion levels were formed through a variety of processes including ethane dehydrogenation, producing ethylene as the only primary unstable product. Ethylene underwent very rapid reactions through carbenium ion intermediates, producing aromatic hydrocarbons and C1-C4 hydrocarbons as secondary products.
