The invention is concerned with novel apparatus and process for converting crude carbon such as coal, carbonaceous wastes and the like into valuable chemical products and/or energy. A mass of solid crude carbonaceous fuel is fed into a high temperature liquid which acts as a solvent for carbon at a temperature sufficient to carbonize the mass and by which the carbon is separated from impurities. Volatile fractions are removed from the mass which acts as a distillation column. Air, or another oxygen source, is introduced into the reactor wherein it reacts with the carbon dissolved in the liquid therein, which may preferably be iron to form a hot fuel gas. The hot fuel gas is then used to produce useful energy, generally via a stepwise procedure.
