Effect of thermal dissolution treatment on viscosity of coal - oil slurry 热溶预处理油煤浆的粘度变化
Effect of particle size distribution on the rheology of oil - coal slurries 煤颗粒分布对油煤浆流变特性的影响
The rheological behavior of shenhua coal - oil slurry was studied as a function of solids concentration , particle size and size distribution 摘要采用神华煤和煤直接液化循环油配制成油煤浆,考察了煤的颗粒大小、颗粒分布以及浓度对煤浆流变特性的影响。
The results indicate that , with a careful control of the particle size distribution , it is possible to prepare an optimum oil - coal slurry which has a low viscosity but with high solids loadings 因此,改变煤浆体系中煤的颗粒分布可在保持较高浓度时制备出具有较低黏度的油煤浆。
