摘要
用二硫化碳－Ｎ－甲基－２－吡咯烷酮（ＣＳ２－ＮＭＰ）混合溶剂对五种不同煤阶煤进行了萃取，考察了煤的可溶性与粘结性的关系。结果表明，煤的可溶性与粘结性密切相关。由此提出煤中主要存在“致粘组分”和“不粘组分”的概念，即煤在ＣＳ２－ＮＭＰ中的萃取物为致粘组分，萃余物为不粘组分。
Five coals with different coal ranks were extracted with carbon disulfide N 2 pyrrolidinone (CS 2 NMP) mixed solvent.The relationship between their solubilities and coking properties was examined.The results show that their solubilities are closely related to their coking properties.The concept of “coking composition” and “non coking composition”,i.e.,the extract from the coals with CS 2 NMP acts as coking composition but the residue acts as non coking composition,is thereby put forward.
