摘要
The sequential thermal dissolution of huolinguole lignite in methanol and ethanol was reported. HL was pulverized to pass through a 200-mesh sieve followed by drying in a vacuum at 80°C for 48 h. The 4 g of HL and 30 mL of methanol or ethanol were put into a 100 mL stainless-steel, magnetically stirred autoclave and after drawing most of the air out from the autoclave with a vacuum pump at room temperature, the autoclave was heated to 200° C and maintained at that temperature for 2 h. The autoclave was cooled to room temperature in a water bath, and the reaction mixture (RM1) was taken out from the autoclave and filtrated to separate RM1 into filtrate (F1) and filter cake (FC1). The significant increases in total yields (TY) of methanol-extractable fraction (MEF) and ethanol-extractable fraction (EEF) were initiated from 270 and 240° C and reached 23.0 and 55.3% at 330° C, respectively.
