Abstract

The influence of sulfated catalysts ZrO2 and ZrO2–Al2O3 on conversion of supercritical ethanol was studied. It was shown that the catalyst and process temperature have a significant influence on the of liquid and gaseous products composition. The main reaction pathways of ethanol conversion at 300 °C are ethanol dehydrogenation followed by conversion of formed acetaldehyde to 1,1-diethoxyethane, and ethanol dehydration to dimethyl ester. The temperature increase to 400 °C accelerates the reactions of ethylene formation and oligomerization, as well as conversion of primary products to a wide range of oxygen-containing substances
