Study of preparation method and oxidization/reduction effect on then performance of nickel-cerium oxide catalysts for aqueous-phase reformingn of ethanol

摘要

The effect of preparation method and oxidation state of the active metal on the catalytic activity of Ni-Ce -O catalysts was studied for aqueous phase reforming of ethanol. A sol-gel (SG) route and a solution combustion synthesis (SCS) method were used for the preparation of 10 wt% Ni loaded catalysts. The catalytic activity of three groups of catalysts; reduced at 425 degrees C (HR, metallic Ni), reduced at 1000 degrees C (FR, metallic Ni), and not reduced (NR, as NiO) were tested at different
