IMPACT OF COAL TAR DISTILLATES ON LIQUID YIELD BY MICROWAVE-ASSISTED EXTRACTION
摘要
Abstract
Using coal tar distillates as solvent, coal microwave-assisted extraction was investigated in this paper. On the basis of experiment, the effect of solvent/coal ratio, microwave radiate time on the extraction yield was discussed. The liquid yield can reach up to 25. 51% at the optimal extraction conditions with solvent/coal ratio of 3:1 and radiating time of 20 min, which implies a new utilization way for low carbonization coal tar. Dry ash-free basis coal and its residues were examined with FT-IR and SEM, which indicated that residual-coal's (H/C) is decreased and the macromolecular network of coal is not ruined after extraction.关键词
