摘 要: 水煤浆 ( CWS)是一种新型煤基液体燃料 .分散剂是水煤浆添加剂中的主要组分 ,是决定水煤浆性能的关键 .对水煤浆工业中普遍使用的阴离子型分散剂包括萘系、聚烯烃系、聚羧酸系、腐殖酸系和木质素磺酸盐系分散剂进行了评述 ,对非离子型分散剂和复配分散剂作了介绍 ,探讨了分散剂的分子结构对煤浆的流变性和静态稳定性的影响 ,并对水煤浆分散剂的研究开发与工业应用前景作了展望 . Coal water slurry(CWS) is a new unpolluted liquid fuel replacing petroleum. The dispersant is the main component in the additives of CWS, which is the bottleneck determining the performance of CWS. The species of the anionic dispersant used extensively in the CWS industry including naphthalene series, polyolefine series, polycarboxylate series, humic acid series and lignosulphonate series are summarized.Furthermore,the non-ionic dispersant and the formulated dispersant are introduced.Moreover,the effect of the molecular structure of the dispersant on rheological property and stability of the CWS is discussed, and a perspective in the research development and application prospect of CWS is given.
