摘　　要：生物质经厌氧发酵产生的沼气富含甲烷与二氧化碳,两者都是主要的温室气体,然而经适当净化后,沼气又是可再生的清洁能源,可以有多种利用方式。从沼气中分离出甲烷并通过催化重整可以制取氢气,具有环境与经济的双重效益。本文对比了沼气重整制氢的各种方法,指出通过干重整是沼气重整制氢的最优途径。Biogas produced by anaerobic fermentation of biomass enriched methane and carbon dioxide, which were the main greenhouse gases. However, biogas was a reproducible clean energy sources after being purified, and had many usages. Methane separated from biogas can produce hydrogen by catalytic reforming, which had environmental and economic double benefits. The methods of biogas reforming to hydrogen were compared and it was indicated that dry reforming was the optimal approach.
