不同煤阶煤干馏制焦炭过程中结构变化的研究

Study on structural changes in different coal rank during coking process by dry distillation

煤的焦化是煤炭加工利用方面最成熟、时间也最长的工艺,但是由于煤组成结构的复杂性、多样性及不均一性,时至今日,对于焦化的研究仍然是实践经验多于理论的发展。以平朔煤和神东煤作为代表,通过采用XRD、Tg-DSC、FT-IR等手段对煤干馏前、后物质进行了研究。

Coal coking is the most mature and longest process in the coal processing and utilization. But because of the complexity,diversity and inhomogeneity of the coal composition,there is much more research of coking than the theory. Taking Pingshuo coal and Shendong coal as representatives,the matter before and after dry distillation of coal was studied by means of XRD,Tg-DSC and FT-IR.
