Dispersions of solid fuel in oil.

摘要

Dispersions of a friable solid fuel in oil are prepared by grinding coal together with a minor proportion of green petroleum coke in a fuel oil medium. Air is excluded from the grinding operation and the mean particle size of the solid fuel particles is reduced to a value in the range 1 to 15 micron. The dispersion contains 15 to 55% by weight of solid fuel. The presence of the coke enhances the stability of the dispersions which are suitable for use as industrial fuel oils.
