摘　　要：对目前的沼气应用状况及未来的应用前景进行了介绍和探讨,提出了一些需要解决的关键技术。中国的沼气应用目前主要为直接燃烧,其利用价值较低,未能充分发挥其经济与环境效益。作为近期目标,可以扩大沼气发电和车用沼气应用规模,从长远来看,可以发展沼气燃料电池和沼气化工来提高沼气的应用价值。为此,应首先实现农村沼气规模化集中生产与供给,结合不同的利用方式选择不同的净化和储存技术,积极开展沼气催化合成技术,为将来的沼气化工产业做技术储备。The present status of biogas utilization is introduced and its future utilizing perspective is pointed out. The current uthilzing way is direct burning, which just has low utility value and can not bring the economical and environmental benefit into full play. As a short-term objective, biogas power generation and vehicle biogas production will be increased continuously;and as a long-term objective, biogas fuel cell technology and biogas chemical industry should be developed to improve the utility value of biogas. Therefore, rural blngas producing and supplying centralized ought to be carried out firstly, then suitable scrubbing and storage technology should be developed and selected based on the utilizing pathway. At the same, biogas catalyzing synthesis technology needs more study as a technical reservation for biogas chemical industry.
