STEAM CONVERSION OF ETHANOL TO HYDROGEN OVER CO-CE-O CATALYSTS

Abstract

In the offered article, the reaction of steam conversion of ethanol to hydrogen over binary cobalt-chromium oxide catalysts was explored. It had been found that at temperatures up to 400°C, ethanol is mainly converted into ethyl acetate. It is shown that with increasing reaction temperature, the yield of ethyl acetate passes through a maximum. At the high temperatures of the ethanol steam reforming reaction, the main reaction product is hydrogen. The peak yield of hydrogen is detected over the catalyst Co: Ce=1:9 at 650°C and is equal to 89.9%. It has been demonstrated that carbon monoxide and methane are by-products of the reaction of the steam conversion of ethanol into hydrogen.
