摘要：

Asbestos-derived ZSM-5 and steam-treated ZSM-5 zeolites, as well as ZSM-5 zeolites having a Si/Al atomic ratio ranging from 35 to 55, have been found to be very active and selective in the conversion of aqueous ethanol to ethene at about 300°C. This was attributed to a moderate surface acid density of these catalyst which seem to be suitable for the Bioethanol-to-Ethylene process. © 1990.
