油煤浆中溶剂的黏度与油煤浆黏度关系的研究

Study on the relationship of viscosity between coal slurry and solvent in coal slurry

安庆芳烃萃取油是理想的煤液化起始溶剂的原料,常压,100℃以下用德国Haake旋转黏度仪测定了不同加氢次数安庆芳烃萃取油的黏度,神华煤液化循环溶剂的黏度及其相对应的干煤浓度为45%的煤浆黏度变化,提供了油煤浆中溶剂的黏度与油煤浆黏度关系的一种方法。

Anqing aromatic hydrocarbon extract oil is a kind of ideal material of initial solvent for coal liquefaction. The viscosity change of three substances have been determined by German Haake rotary viscosity meter at normal pressure, below 100℃. The three substances are as follows： Anqing aromatic hydrocarbon extract oil with different hydrogenations, liquefaction cycle solvent of Shenhua coal and their corresponding coal slurry in which concentration is 45% based on dry coal, The relationship of viscosity between coal slurry and solvent in coal slurry was found.
