研究了内蒙某褐煤制油煤浆在高温高压条件、不同浓度和不同升温速率条件下黏度变化规律,为0.1 t/d褐煤直接液化实验提供初步的基础数据.选用煤炭科学研究总院研制的模拟高温高压条件下油煤浆黏度变化的高压釜,通过记录高压釜扭矩变化来换算成油煤浆黏度.结果采用线性回归方法,得出了该褐煤制油煤浆在高温高压条件下黏温关系方程.通过黏温关系方程,可以计算在不同温度下该油煤浆的黏度.结果表明,在不同升温速率和不同浓度下,该油煤浆黏度随温度升高呈下降趋势,浓度是影响黏度的重要因素.

CT In this paper, lignite of Mongolia, oil-coal slurry under the conditions of high temperature and pressure, different concentrations and different heating rates under the conditions of the viscosity variation, given 0.1 t/d brown coal direct liquefaction pilot data provide an initial basis. The use of autoclave developed by China Coal Research Institute, autoclave torque by recording the changes in converted oil-coal slurry viscosity by linear regression method, obtained oil-coal slurry system under the conditions of high temperature and pressure viscosity-temperature relationship equation. Through the viscosity-temperature relationship equation can be calculated the oil-coal slurry viscosity at different temperatures. From the test results, at different heating rates and different concentrations of the oil-coal slurry viscosity decreases with temperature decreasing trend in the concentration of important factors affecting the viscosity.
