Low-Temperature Hydrogen Production from Woody Biomass by Catalytic Decomposition of Pyroligneous Acid over Ni-based Catalysts

摘要

Hydrogen is of great interest as the clean fuel for power generation using fuel cells or transportation in response to exhausting fossil fuel and environmental protection. The conversion of woody biomass into hydrogen can be thermochemically achieved via gasification combined with pyrolysis, steam reforming, oxidative steam reforming or autothermal reforming. Pyroligneous acid, principally composed of acetic acid, acetone and methanol, could be obtained by the dry distillation of woody biomass. It is propitious for the advanced utilization of distributed biomass sources because it is easily transportable and is conveyable to hydrogen via catalytic steam reforming. Catalytic steam reforming of ethanol, model compounds like acetic acid and acetone, toluene, diluted bio-oil with methanol, bio-oil over various catalysts has been widely investigated [1-3]. However, these processes usually performed at high temperature from 773 K to 1173 K.
