在不添加任何催化剂的情况下，在350 ~ 475℃的不同温度下，对三种澳大利亚烟煤的惰铁精矿进行了加氢。苯提取加氢残渣的转化率和显微观察结果表明，惰质组显微组分的加氢作用仅在400℃左右发生，而伴随的镜质组显微组分的溶解加氢作用主要发生在350 ~ 400℃之间。在加氢过程中，惰质颗粒的主要反应途径是先轻度碳化后加氢。提出了一种简化的反应方案，描述了惰铁加氢的反应途径。
Inertinite concentrates from three Australian bituminous coals were hydrogenated at various temperatures ranging from 350 to 475 °C in the presence of tetralin without any added catalyst. Both conversion yields and microscopic observations of the benzene-extracted hydrogenation residues have revealed that the hydrogenation of the inertinite macerals becomes significant only > 400 °C, whereas the dissolution-hydrogenation of the accompanying vitrinite macerals occurs mainly between 350 and 400 °C. The major reaction pathway for the inertinite particles in the hydrogenation process appears to be one of initial mild carbonization followed by hydrogenation. A simplified reaction scheme is proposed which describes the reaction pathway involved in the hydrogenation of inertinite.
