REDUCING GAS GENERATION (D#72,518-F) ABSTRACT OF THE DISCLOSURE Gaseous mixtures comprising principally H2 and CO are made by the noncatalytic partial oxidation of a hydrocarbonaceous fuel in the reaction zone of a gas generator in the absence of supplemental H2O other than any which may be produced by the process or that which may be initially present in the reactants as an impurity. Supplemental NH3 in an amount in the range of about 0.01 - 1.00 lbs. of NH3 per lb. of hydrocarbonaceous fuel is introduced into the reaction zone as a temperature moderator. Reducing gas may be produced thereby at a lower reaction temperature i.e. preferably in the range of about 1500 to 3500°F, and a pressure in the range of about 1-350 atmospheres, and with an improved quality. Thus, the effluent gas stream from the reaction zone may have a reducing ratio e.g. mole ratio (H2+CO)/(H2O+CO2) of at least about 10, and usually in the range of about 15 to 100. I
