摘要(Abstract)：

通过高压釜在溶剂和催化剂条件下对煤的加氢液化试验,探讨了低煤级煤中煤岩组分的液化性能。结果表明,在不同宏观煤岩成分的液化试验中,转化率和油产率表现出镜煤>亮煤>暗煤>丝炭;对于显微组分的液化,不仅镜质组和壳质组具有反应活性,半镜质组也有一定活性,且活性组分(镜质组+半镜质组+壳质组)含量与液化转化率、油产率表现出良好的正比关系。低煤级煤中,Rmax<1.50%的半丝质组分在液化时有反应活性,其活性低于同一煤中的半镜质组,而Rmax>1.50%的惰质组分已不具反应活性。
In this paper,the liquefaction reactivity of the lithotype and maceral of low rank coal was studied in autoclave when solvent and catalyst were used in the hydro-liquefaction test.The experiment results indicate that the conversion and the oil yield are in the sequence of vitrain,clarain,durain and fusain for macro-lithotype of coal.At the same time,for micro-maceral,not only vitrinite,exinite have activity,but also semi-vitrinite has certain activity,and the content of the active component(vitrinite,semi-vitrinite,exinite) increases linearly with the conversion and the oil yield.Semi-fusinite has activity in liquefaction when the reflectance is less than 1.5%,but its activity is less than that of semi-vitrinite in the same coal,and inertinite does not have any activity when the reflectivity is more than 1.5%.
