摘要
本文从能源转化利用的角度探讨了褐煤转化的研究历史、研究现状及研究前景。中国有丰富的褐煤资源 ,储量达 130 3亿吨 ,其开发利用必须兼顾能源需求和环境保护两个方面 ,走可持续发展的道路。关于褐煤转化的工业途径可概括为四大类 :即褐煤的热解和炼焦 ,褐煤气化 ,褐煤液化 ,及褐煤化学提取腐植酸制品 ,而褐煤微生物转化与利用研究起步较晚 ;文中主要从褐煤降解微生物的分离 ,褐煤微生物降解的机理 ,褐煤微生物降解产物的优越性等方面对其进行了论述 。
The research history, actuality and foreground of lignite transformation were discussed in this paper. There is abundant lignite resources in China, with reserve reaching 1303 hundred million tons, so it must be exploited and used from aspects of energy sources transforming utilization and environmental protection to keep sustainable development. The industrial utilization about lignite includes four aspects: lignite pyrogenation and coking, lignite gasification, lignite liquefaction and extraction of humic acid from lignite. But the study on microbial degradation of lignite started lately. This paper emphasized on isolation of degradative microorganism, mechanism of microbial degradation, advantages of microbial degradation products and the prospect of microbial utilization of lignite.
