论煤岩组分的液化性能

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，R_max<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R_max>1.50%的惰质组分已不具反应活性。 

Discussion on liquefaction reactivity of lithotype and maceral of low rank coal

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%.
