Abstract
Ground coal is dispersed in an aqueous electrolyte and is alternately oxidized anodically and reduced cathodically. The reaction gases and the liquid hydrocarbons obtained and other volatile organic compounds are processed and used in the customary manner. The reactive groups formed in the coal improve its cokeability, extractability and capacity for hydrogenation. In addition, the treated coal because of its good wettability, suspended in water or alcohol, is well suited as a liquid fuel or motor fuel.
