以红泥和硫磺为催化剂，研究了穆斯韦尔布鲁克煤液化残渣（简称液化残渣）和与之相关的三芳氮杂芳烃的氢解反应。在苯并[f]喹啉与苯并[f]喹啉的反应中，苯并[f]喹啉向二氯甲烷可溶物的转化被抑制。吖啶和异硫氰酸酯的反应对异硫氰酸酯的改性有一定的促进作用。在邻苯二甲酸和菲啶的反应中，邻苯二甲酸氢解生成二氯甲烷可溶物的过程得到了促进，而生成正己烷可溶物的过程受到了抑制。在苯并[h]喹啉与苯并[h]喹啉的反应中，由于苯并[h]喹啉的溶解和分散，催化剂对苯并[h]喹啉杂环部分的毒性很小，从而有效地进行了混合物的改性。因此，苯并[h]喹啉的溶剂效应促进了苯并[h]喹啉的改性。从穆斯韦尔布鲁克煤液中分离出的碱性馏分与正己烷的反应中，正己烷可溶物的增加和二氯甲烷不溶物的减少对煤的改质具有协同效应。因此，认为碱性馏分中具有类似于苯并[h]喹啉和菲啶骨架结构的化合物促进了苯并[h]喹啉和菲啶的升级。
The hydrogenolysis reactions of Muswellbrook coal liquefaction residue (CLR) and triaromatic azaarenes related to the basic coal liquid were investigated by using red mud and sulfur catalysts. In the reaction of CLR and benzo[f]quinoline, the conversion of CLR to dichloromethane soluble was depressed. The upgrading of CLR was slightly enhanced in the reaction of CLR and acridine. In the reaction of CLR and phenanthridine, the hydrogenolysis of CLR to dichloromethane soluble facilitated; however, the upgrading to n-hexane soluble was depressed. In the reaction of CLR and benzo[h]quinoline, since benzo[h]quinoline dissolved and dispersed CLR, upgrading of the mixture occurred effectively by the catalyst poisoned little for heterocycle moiety of benzo[h]quinoline. Therefore, the upgrading of CLR was enhanced by the solvent effects of benzo[h]quinoline. In the reaction of CLR and basic fraction separated from Muswellbrook coal liquid, the synergistic effects to upgrading, such as the increase of n-hexane soluble and the decrease of dichloromethane insoluble, have been observed. Consequently, it was considered that the upgrading of CLR was facilitated by the compounds having the skeleton structure similar to benzo[h]quinoline and phenanthridine in the basic fraction.
