Abstract

The conversion of ethanol on zeolite catalysts is studied spectrokinetically in situ. Ethoxy groups and polyene structures (compaction products) are found to be key intermediates on the studied catalysts under reaction conditions. Ethoxy groups are shown to convert into diethyl ether by a bimolecular mechanism at relatively low temperatures in the presence of ethanol in the gas phase. The character of the conversion of ethoxy groups is found to change at temperatures above 200°C: they become a source for the formation of surface polyene structures, which in turn are converted into a complex combination of hydrocarbons.
