生物质气体燃料概述与展望

Survey and Development of Biogas Energy

论述了生物质气体燃料的种类以及生产各种气体燃料的相应技术及其国内外发展概况和存在问题。生物质气化方面国内外有产业化实例;生物发酵制氢大多数处于实验阶段,关键是培育高效产氢发酵菌种、进一步提高系统的产氢能力、降低生产成本;厌氧发酵制取沼气生产技术比较成熟,在其生产过程中不消耗其它能源、没有环境污染、而且可降解各种有机废弃物,是目前最有希望的生物质能源之一。

The varieties of the biomass energy, the technologies for producing all kinds of biomass energy, development survey at home and abroad and the existence problems are discussed in this paper. There were many Industrialization examples in the biomass gasification field at abroad; but making hydrogen gas was on the experiment phase by ferment biomass, the key to cultivate new zymogens to increase produce hydrogen gas by fermenting biomass, in order to improve producing hydrogen gas capability of system and to reduce produce cost. The technology of producing biogas is relative mature in gas fuel, which don＇t consume other energy sources nor pollute the environment, also decomposes various organic rejectamenta during producing the biogas. So the biogas is the one of most hopeful biomass energies currently.
