STABILIZATION OF LOW RANK COALS AFTER DRYING
A method of increasing the utility of low rank coal of high moisture content by stabilizing essential physical properties of the coal, following its drying by known methods, which without stabilization render it unsuitable for transportation and storage. The method employs controlled partial pyrolysis in a continuous flow configuration, using electromagnetic energy in novel ways. The stabilization an be carried out by this method at the very high rates required for commercial coal operations.
