摘要(Abstract):
煤的液化潜力与煤岩成分和煤化作用程度有着密切的关系,更进一步研究煤岩成分中不同显微组分对液化的影响,探讨显微组分的结构,将对优质液化煤的讦价起重大作用。煤中不同的显微组分具有不同的光性特征,镜质体反射率是划分煤阶的主要参数,但是煤的全显微组分反射率的研究把煤岩成分与煤阶结合起来,对液化煤进行综合评价。本文介绍了国外这方面最近的一些研究成果:1.镜质组和壳质组具有非常类似的转化率,但是抽提产物中族组分却存在显著的差异,镜质组主要出现前沥青烯和沥青烯,而壳质组主要出现油和气。2.低反射率惰性组显微组分虽然转化率较低,但是主要产出油和气。3.相对未凝胶化的显微组分具有较高的油产率,而较高凝胶化程度的显微组分油产率却较低。4.煤的全显微组分反射率分布可以预测煤的液化潜力。
