Abstract
Low rank solid fuels are upgraded by heating a mixture of particulate fuel and water to a temperature between 300.degree. F. and the critical temperature of water under a pressure sufficient to maintain substantially all of the water in liquid state, cooling the mixture and separating the particles from the water by agglomeration with a hydrocarbon liquid.
