摘 要: 选用3种不同煤化程度的煤和2种添加剂制备水煤浆,研究煤化程度对制浆性质的影响;用木质素磺酸钠(sodium-lignosulphonate,SLS)与萘磺酸钠甲醛缩合物(NSF)及其复配分散剂进行制浆试验,研究这2种分散剂对制浆性能的影响及其协同作用。通过对3种煤进行成浆试验,结果表明:对于3种不同煤化程度的煤样,SLS分散剂的成浆性能比NSF差;低变质煤样成浆性较差,且通过分散剂的复配并不能够明显提高其成浆性;高变质煤样的成浆性较好,且通过分散剂的复配能够明显提高其成浆性。
关 键 词: 煤化学工程;复配分散剂;成浆性;煤化程度;流动性;稳定性

Abstract: In this paper, the promoter action of different dispersants on coal�s slurry ability has been studied by using 3 kinds of coals in different ranks, to study the influence of coal rank on character of coal�s slurry. The experiment uses sodium-lignosulphonate(SLS) and naphthalenesulfonic acid-formaldehyde condensate (NSF) as additives. The synergistic effects of SLS and NSF and their compound dispersants have been researched yet. The results show that: the SLS dispersant has lower slurry property than the NSF to the three coal samples with different ranks; the low-rank coal has low slurry property, which can not be obviously increased by recomposing dispersants; and the high-rank coal has high slurry proerty, which can be obviously increased by recomposing dispersants.
Key words: coal chemistry engineering; compound dispersant; slurry ability; rank of coal; fluidity; stability
