Abstract

A process is disclosed for the preparation of stable mixtures of coal and oil comprising the following steps:
a) grinding of the coal down to a particle size lower than 200 µm;
b) mixing of ground coal with water;
c) mixing of moisturized coal with oil, a mixture being obtained with coal content not greater than 50% by weight, and with a water content not greater than 20% by weight relatively to the mixture itself;
d) homogenizing by fine subdivision of the components of the mixture as under point (c).
