Alcohols such as methanol, ethanol, and glycerol are potentially produced from biomass. For example methanol can be made from bio-syngas that is produced by gasification of lignocellulosic biomass. Ethanol is produced by yeat fermentation of glucose derived from starch or cellulosic biomass. Glycerol is generated as a byproduct during biodiesel production. In this work, methanol, ethanol, and glycerol were steam reformed to produce hydrogen-rich gas that can be directly used as a fuel in a fuel cell system for electricity production. The effect of alcohol concentration and feeding rate on the generation rate and composition of gaseous product was investigated over Ni-Y/AC catalyst packed in a continuos-flow reactor. Gas production rates of methanol, ethanol, and glycerol were over 1.4, 1.8, and 1.2 m3/h/L, respectively. Hydrogen content of the gaseous products was over 60 vol% for almost all the experimental cases. |
