Abstract
The reaction of ethanol conversion over binary copper-cerium and copper-tungsten oxide catalysts was studied. It found that the activity of examined samples depends both on temperature reactions and their composition. It revealed that on examined copper containing catalysts, the dependences of acetic aldehyde and acetone yields on the composition of the catalyst have the form of curves with two maxima which is apparently due to changes in the phase composition of binary copper containing catalysts. It established that in the reaction of ethanol conversion over cerium copper oxide catalysts the formation of ethyl acetate proceeds on weakly crystalline samples, and the formation of acetaldehyde on medium crystalline samples. It indicated that increase in the degree of crystallinity of binary copper-tungsten oxide catalysts leads to increase in the yields of ethanol partial oxidation products and to decrease in the yield of carbon dioxide.
