RHEOLOGICAL PROPERTIES OF COAL OIL MIXTURES:
2018-6-13 Coal samples having different ash and moisture contents have been used to study the effect of these components on rheological properties of coal oil mixtures. It has been observed that coals having higher ash content give rise to less viscous coal oil mixtures and viscosity of the COM decreases as moisture content of coal is reduced.
