| 摘 要： | 讨论了煤炭直接液化过程中溶剂的特点、作用及质量要求，煤液化溶剂具有一般溶剂的功能，同时还具有良好的供氢和传递氢的功能特点，起到溶解、分隔煤裂解生成的自由基的作用，溶剂必须具有一定的分子结构和分子大小。初步讨论了表征煤液化循环溶剂供氢性的指标，指出普通溶剂如四氢萘和二氢萘等部分饱和的芳香化合物可直接用作煤液化溶剂，多环芳烃含量较高的煤焦油和石油系重质油，经过预加氢处理提高溶剂的供氢性后，可作为煤液化过程的起始溶剂或替代溶剂。

| Abstract: | The characteristics,functions and quality requirements of solvents for direct coal liquefaction were discussed.Not only having the function as much as other solevents,the solvents for direct coal liquefaction also have the functions of providing and transferring active hydrogen,and dissolving,dispersing free radicals from coal cracking.The solevent need to have proper molecule structure and size.The quality indexes of hydrogen donor solvents were preliminarily discussed.The results show that the general sol... |
