IMPROVED PYROLYSIS PROCESS FOR CONVERTING REFUSE TO FUEL GAS ABSTRACT This invention relates to improving the known process for disposing of refuse while simultaneously pro- ducing a useful gaseous product and an inert solid residue in a shaft furnace in which refuse is fed into the top por- tion of said furnace, an oxygen containing gas is fed into the base, and in which the organic portion of the refuse is pyrolized to char, oils and gas containing a high concentra- tion of CO and H2, and the inorganic portion of the refuse is fluidized and tapped from the base of the furnace. The improvement in the above-described process comprises removing a portion of the char from the furnace while retaining a sufficient amount of combustible materials in the furnace to satisfy the energy requirements of the process. The improvement permits a reduction in the oxygen requirements of the process and has a beneficial effect on the specific heating value of the fuel gas produced.
