摘　　要：研究掺混不同比例煤泥制备水煤浆,考察浆体成浆性能和气化反应特性的变化,并通过粒径分布、表面形貌、Zeta电位等分析了原因。结果表明:添加煤泥改善了水煤浆成浆性能,浆体流变性变好,呈现更强的假塑特性,稳定性增强,降低了煤泥水煤浆的气化反应温度,延长气化反应区间。The blending different proportion slime coal water slurry preparation, analyse the slurryability and gasification reaction characteristic of prepared coal water slurry. The results show that, adding coal slurry to improve the coal water slurry into slurry performance, slurry rheologieal property and stability, present better pseudoplastic characteristic, the addition of coal slime can reduce gasification reaction temperature and prolong the gasification reaction range of slime coal water slurry.
