马家塔煤及其显微组分的加氢液化特征

用Fe2O3作催化剂，硫黄为助催化剂，脱晶蒽油为循环溶剂，在反应温度为450度，初始氢压为10MPa，反应时间为60min的实验条件下，在微型高压釜内对马家塔原料煤及其显微组分的加氢液化特征进行了系统研究，镜质组的液化反应性高于惰质组，在原料煤，镜质组和惰质组这三种实验原料中，原料煤的液化反应性是最高的，对总转化率和油收率而言，原料煤＞镜质组＞惰质组，对沥青烯产率而言，原料煤＞惰质组＞镜质组，水产率则是镜质组＞原料煤＞惰质组，气产率为惰质组＞镜质组＞原料煤，原料煤，镜质组和惰质组在加氢液化过程中所产生的气体在组成上也是有所差异的，各显微组分在加氢液化过程中可能存在着协同作用。

HYDROLIQUEFACTION CHARACTERISTICS OF MAJIATA COAL AND ITS MACERALS COMPONENTS

The hydroliquefacton characteristics of Majiata coal and its individual macerals were systematically investigated in a microautoclave at the following experimental conditions: reaction temperature of 450 ℃, initial H2 pressure of 10 MPa, residence time of 60min., decrystallized anthracene oil was used as a solvent, Fe2O3 plus sulfur as the catalyst. The hydroliquefaction reactivity of vitrinite is higher than that of inertinite, and the parent coal has the highest hydroliquefaction reactivity among these three feedstocks. The reactivity order for the total conversion and oil yield is: parent coal＞vitrinite＞inertinite, for asphaltene yield: parent coal＞inertinite＞vitrinite, for water yield: vitrinite＞parent coal＞inertinite, for gas yield: inertinite＞ vitrinite＞parent coal. The composition of gas from hydroliquefaction of the parent coal, vitrinite and inertinite is different. Synergism between the individual macerals during hydroliquefaction process exists.
