生物质能的应用前景分析

Prospects for the utilization of biomass energy in chemical industry

生物质能是可再生能源的重要组成部分,生物质能的高效利用,对解决能源和生态环境问题将起到十分积极的作用。概述了目前生物质能的主要转换方式。化学转变中的液化、气化和热解技术是目前主要研究方向。通过液化、热解可以直接得到一些化工产品;通过气化可以得到合成气,可以用来合成氨或者甲醇。总之,通过这些转变不但可以得到一些化工产品,而且可以缓解化石能源枯竭带来的能源危机。

Biomass energy is one of the important renewable energy resources and its effective utilization will exert a great influence on solving energy and environmental problems. In this paper, the main methods for biomass energy conversion are summarized. The chemical conversion techniques, e.g. liquefaction, gasification and pyrolysis, are the main orientation for research and development. Through liquefaction and pyrolysis, some valuable chemical products can be obtained, and through gasification we can get synthetic gas which can be used for synthesizing ammonia or methanol. In a word, the conversion techniques can help us to obtain valuable chemical products and to reduce the influence of energy crisis produced by the increasing shortage of fossil fuels.
