摘　　要：通过煤质分析,挑选出了适合宁东甲醇厂德士古水煤浆(CWS)加压气化工艺的宁东地区原料煤———羊场湾矿,遴选出了适合羊场湾矿煤制水煤浆的木质素磺酸盐分散剂,同时考察了不同来源木质素磺酸盐分散剂对该水煤浆的粘度影响规律,并确定了分散剂最佳掺量为1%.By properties and analysis of coal in Ningdong area,a coal species suited to texco gasification process has been found in Yangchangwan mine.A kind of lignin sulphonate is adaptive to the coal-water-slurry of Yangchangwan mine.The different quarry of lignin sulphonate has been studied to the coal-water-slurry of Yangchangwan mine.The performance of coal-water-slurry is the finest when the concentration of lignin sulphonate dispersant is 1%.
