Hydrogen Production via Catalytic Partial Oxidation of Butanol over Ni-based Catalysts

摘要

Hydrogen is an important energy carrier, especially for application in fuel cell. Besides reforming of natural gas and coal, reforming of biomass-derived alcohols, e.g., butanol, is a promising route for hydrogen production. Availability of butanol can be improved by improved strains of bacteria to break down and ferment biomass, especially from cellulosic resources. Compared with ethanol, butanol has more carbon atoms and more energy, but is more difficult to be activated for hydrogen production. Catalytic partial oxidation (CPOX) of butanol can be an effective route, in which butanol can be converted and oxidized into CO or CO2 with H2 production. Within the CPOX process, sintering and oxidation of active components are main concerns for a stable catalyst. In addition, the carbon deposition or coking cannot be neglected, because carbon could be extracted and cover the active sites and block the channel of catalyst bed, and results in deactivation.
