摘要：煤中的低分子化合物一般是指分散于煤的高分子主体结构中的分子量小于500的有机化合物。对6种煤用苯在加压下抽提出沥青后,发现煤的炼焦性质几乎完全破坏。本文讨论了作用机理和有关问题。
Low molecular weight compounds of coal is generally defi- ned as those organic compounds with MW below 500 destributing in skele- ton structure of coal macromolecular material.Using 6 bituminous coals in different ranks a series of benzene extraction experiments were performed under the condition——280℃,5 MPa and 3 h.The coking behaviours of coal samples after benzene extraction were almost totally destroyed.The func- tion mechanism and related problems were also discussed.
