Abstract

PURPOSE: A process for preparing metallurgical coke, by [I] adding bituminous substances with a specific softening point to the stock coal to which non-or weakly-caking coal is concentrated, [II] forming the said coal into briquets having a specific volume and a specific density, [III] mixing the said briquets with powder coal and [IV] drying the mixture by distillation, while reforming the briquets in the dry distillation step and increasing the expansion force of the briquets.
