THE ACTIVITY OF THE ZINC–COBALT OXIDE SYSTEM IN THE REACTION OF ETHANOL STEAM REFORMING

Reaction of ethanol steam reforming to hydrogen over binary zinc–cobalt oxide catalysts of different compositions has been studied. It is found that at low temperatures the reaction products are acetaldehyde and acetone, whereas at high – hydrogen and carbon dioxide. It is shown that in the reaction of formation of hydrogen the most active samples are composition Zn:Co = 2:8 and 9:1. The highest yield of hydrogen over studied catalysts reaches 74.3% at ethanol conversion equal 95%
