Abstract
A stable, uniform solvent refined coal (SRC)--oil dispersion is prepared by grinding 15 to 55% by weight of SRC particles in the absence of free oxygen in a medium consisting essentially of gas oil and/or a heavier petroleum fraction. Grinding is continued until the size of the majority of the particles is reduced to a value in the range 1 to 10 micron. Preferably the SRC is uniformly dispersed in the gas oil and/or heavier petroleum fraction prior to grinding.
