摘要
研究了胜利煤在N-甲基吡咯烷酮(NMP)、N,N-二甲基甲酰胺(DMF)、环己酮(CHO)等12种单一溶剂及其混合溶剂作用下的溶胀效果,实验结果表明,吡啶、DMF、糠醛-CS2、丙酮-CS2、NMP-CS2、甲醇-丙酮等混合溶剂对煤的溶胀效果较好,并考察了该6种混合溶剂对煤进行溶胀后用旋转蒸发仪回收的产率。
A study was undertaken to evaluate the effect of Shengli coal swelling in different solvents,which not only include single solvents but also mixtures of the following substances,N-Methyl pyrrodlidone(NMP),N,N-dimethylformamide(DMF),Cyclohexanone(CHO) etc.The result shows that swelling effects of Pyridine,DMF,Furfural and CS2,Acetone and CS2,CS2 and NMP,and Methyl Alcohol and Acetone are better.Some typical solvents were recovered by the rotary evaporatores after swelling,recovery rate was tested for further industrial application.
