摘要

摘要: 以煤直接液化残渣制备了水渣浆，考察了粒径分布、搅拌时间、分散剂的用量及种类对水渣浆性质的影响。根据实验确定了制备水渣浆的最佳工艺参数：Alfred粒径分布模型（d_280~154μm、d_154~74μm、d_<74μm 质量分数分别为14%、16%、70%），搅拌时间20 min，分散剂加入量为干渣基1.0%。实验结果表明，液化残渣制备水渣浆的定黏质量分数分别为73.5%（NSF）和71.0%（SL）。分散剂萘磺酸盐甲醛缩合物（NSF）的分散降黏效果优于改性碱木质素磺酸钠（SL），而水渣浆的流变性，分散剂SL要优于分散剂NSF。

Abstract: In this work, the slurryability of direct coal liquefaction residue (DCLR) was systematically studied, and the effects of particle size distribution (PSD), stirring time, dosage and types of dispersant on the quality of direct coal liquefaction residue-water slurries (DCLRWS) was investigated. The results show that the dispersancy of naphthalenesulfonate formaldehyde (NSF) is much better than that of sodium lignosulfonate (SL), while the rheology of DCLRWS dispersed by NSF is poorer, which is mainly related to chemical characteristics of SL and NSF and interaction between dispersant with particles. Based on the experiments, the optimum conditions for preparing DCLRWS are determined, as follows: particle size distribution of Alfred model (d_{280~154 μm}, 14%, d_{154~74 μm}, 16%, d_{<74 μm}, 70%), stirring strength, 3 000 r/min; stirring time, 20 min; the dosage of NSF, 1.0%. Under the optimal experimental condition, the maximum concentration of DCLRWS is up to 73.5% and 71.0% by using the NSF and SL as dispersant, respectively.
