摘　　要：煤炭直接液化具有成本低、煤-油转化率高等特点,直接液化用煤对原煤的煤岩煤质有一定选择性,通过对胜利矿区煤岩煤质特征总结分析,结合前人对煤炭直接液化相关的煤岩组分和煤质指标研究成果,对影响煤炭直接液化性能的因素(煤炭宏观和显微煤岩组分特征,对煤炭灰分、挥发分、H/C原子比)进行总结分析。结果表明:胜利矿区各项指标均符合直接液化用煤要求,可作为直接液化原料用煤。The coal direct liquefaction has advantages of low cost,high coal-oil conversion rate etc.Coal for direct liquefaction needs certain selectivity on raw coal petrological and quality features.Through summary analysis of coal petrologic and quality features in the Shengli mining area,combined with previous coal direct liquefaction related coal lithotype and coal quality index studied results,carried out summary analysis for coal direct liquefaction performance impacting factors(coal macrolithotype and maceral features,ash,volatile matter contents and H/C atomic ratio).The result has shown that indicators of coal in Shengli mining area are all accord with coal for direct liquefaction requirements,can be direct liquefaction raw material coal.
