Abstract

Procedure for preparing the expansion of granules of carbon-loaded materials and, especially, of coal shales, characterized by the fact that they are subjected to granules of a paste of said materials, dry, to a pre-heating treatment, under cover These preheated granules are then treated in ambient oxygen, then strongly oxidizing, at a temperature that quickly exceeds the contraction of the substance of said granules, and because the granules containing a low rate of useful carbon for expansion and ferrous oxides, in uniform distribution, for expansion operations.
