神府矿区5-2煤层煤质特征及其气/液化性能评价

Evaluation on gasification and liquefaction performance for No.5-2 coal seam and its coal quality characteristics in Shenfu Mining Area

  • 摘要: 为了查明不同煤质煤炭资源清洁利用的最优途径,实现资源的高效清洁转化,以神府矿区为研究区,利用工业分析、显微组分鉴定等手段,对其5-2煤层的煤岩、煤质特征进行了系统的分析。在此基础上,结合建立的气化用煤和液化用煤评价指标体系,对5-2煤层最佳利用方式进行了评价。结果表明:神府矿区煤质具有低灰、低硫、高挥发分,热稳定性好,黏结性低、可磨性指数较高和较低灰熔点等特点;全区煤质满足固定床固态排渣气化和气流床气化工艺用煤一级指标要求,可作为优质的气化用煤;神府矿区孙家岔、柠条塔、郭家湾,红柳塔和沙沟岔等井田部分区域煤质符合液化用煤指标二级指标要求,可作为直接液化用煤。

     

    Abstract: In order to find out the best way of utilizing coal resources with different coal quality, taking No.5-2 coal seam of Shenfu Mining Area as study objects, the characteristics of coal rock and coal quality are systematically analyzed by means of the proximate analysis and macerals of coal and rock testing. On this basis, in combination with the established gasification coal and liquefaction coal evaluation index system, the best utilization mode of No.5-2 coal seam is evaluated. The results show that coal has the characteristics of low ash, low sulfur, high volatile, good thermal stability, low adhesion, high grindability index and lower ash melting point in Shenfu Mining Area, the whole area of coal meet the first rank indicators of the fixed bed solid-state slagging gasification and entrained flow gasification,can be used as high-quality gasification coal. The coal quality of partial areas in Sunjiacha,Ningtiaota,Guojiawan,Hongliuta and Shagoucha coalfield meets the secondary rank indicators of liquefaction coal,can be used as ordinary direct liquefaction of coal.
