摘　　要：研究了煤的溶胀对生物脱硫的影响,考察了吡啶、NMP、甲醇、丙酮这4种溶剂对煤样的溶胀效果,以及在溶胀条件下红球菌对煤的脱硫作用。结果表明,吡啶、NMP对煤的溶胀效果较好,再经过红球菌脱硫的效果远比采用甲醇、丙酮处理的煤样脱硫效果好。The paper studied the biological desulfurization affected by the dissolved swelling of coal. The paper investigated the dissolved swelling results of coal with pyridine, NMP, methane and acetone. Also the paper investigated the desulfurization function of coal with Rhodococcus under the condition of dissolved swelling. The results showed that pyridine and NMP had a good result in the dissolved swelling of coal and then the result of the desulfurization with Rhodococcus could be better than the result of desulfurization with methane and acetone.
