The hydrogenation liquefaction properties of Chinese coals were evaluated in this paper. Most of the brown coal and young bituminous coal studied were found to be amenable to hydrogenation liquefaction.

近来煤作为能源及化工原料重新受到重视,而煤加氢液化又是制取液体燃料的重要方法。本文介绍我国若干主要煤区媒质加氢适应性评价工作结果。认为我国大多数褐煤及年轻烟煤均具有良好的加氢适应性。讨论了加氢适应性与煤的变质程度,尤其是岩相组成之间的关系。对变质程度相近的煤来说煤的岩相组成对煤的加氢转化性能具有决定性的影响。由于催化剂活性影响煤的转化,使用铁系催化剂能较好区别各种煤的加氢适应性。
