Abstract
For drying organic solid materials such as, for example, brown coals, these materials are, after preheating, treated with saturated steam under a pressure of 5 to 45 bar and at a temperature of 150.degree. to 260.degree. C. Prior to the subsequent upgrading step, the water content can further be reduced by introducing superheated steam and/or a pressure relief, whereupon immediately subsequently an upgrading treatment, particularly a gasification under pressure, a briquetting or a coal liquification, is effected with the sensible or intrinsic heat from the drying stage. Preferably the dried organic solid materials are introduced into the upgrading stage while still being under a residual pressure of the drying stage.
