3245. ----- [SCHARMANN, W.G.] (Standard Oil Development Co.). Production of Fuel Gases. United States Patent 2,527,154, Oct. 24, 1950; appl. filed Oct. 18, 1946, Serial No. 703,989; 9 claims (Cl. 260-449.6). Chem. Abs., vol. 45, 1951, p. 335.

Process is given for producing a marketable pipe line fuel gas from Fischer-Tropsch tail gas. The tail gas is subjected to catalytic gasphase hydrogenation, temperature 650°-850° F. with Fe or Ni catalyst, 500°-750° F. with Co catalyst pressure 100-1,000 p.s.i. The heating value may be still further increased by removal of H₂O and unconverted CO₂. 6 United States patents cited.
