为了提高褐煤利用率,介绍了国内褐煤资源的储量形态、分布。分析了目前褐煤的利用途径,包括共伴生资源的利用、直接燃烧、干燥脱水与成型、气化、液化、制水煤浆与热解。并进一步分析了褐煤热解气、液、固产品的利用方向。提出了褐煤半焦利用的新方法,即利用半焦干法气化,或将半焦和热解废水等制成水煤浆,通过湿法气化制得合成气,再通过甲烷化催化剂将合成气制成甲烷,或将合成气通过费托合成制成汽油柴油。

In order to improve the utilization rate of lignite,the lignite reserves and distribution status was introduced. The utilization ways of lignite,including associated resources utilization,lignite direct combustion,dehydration and briquetting,gasification,liquefaction,py-rolysis and coal water mixture preparation were introduced. Then the using direction of gas,liquid and solid productions of lignite pyrolysis were further investigated. The authors put forward some new utilization methods of lignitic semi-coke, including gasifying the semi-coke by the dry gasification and preparing coal water mixture ( CWM) with semi-coke and pyrolytic waste water. The CWM was gasified to pro-duce syngas by the wet gasification. Then the syngas was used to prepare methane with methanation catalysts, or compound petrol and diesel by Fischer-Tropsch synthesis.
