水煤浆添加剂的研究进展

Development of the additives of coal water mixture

随着世界原油资源的日渐减少及燃煤污染的日趋严重 ,水煤浆作为一种新型的环保型煤基流体燃料日益受到人们的重视。从 70年代至今 ,国内外学者研究过多种添加剂 ,目前制浆用添加剂主要分为阴离子表面活性剂和非离子表面活性剂两大类 ,但高效、价廉。

As the reducing of petrol resource and the pollution of fuel coal becoming more and more hardly,water coal mixture (CWM) as a nwe unpolluted kind of caol liquid fuel have been more and more important.From 1970's to present,the abroad and civil professors have studied a lot of additives.The additives used in CWM howe two kinds:one is negative-ion surfactant and the other is non-ion surfactant,but the additives with high effective,low price and wide fitness are still very few.
