2092. LYNCH, C. S, WASSERBACH, T. B, AND GUY, W. R. F. (Standard Oil Development Co.). Method of Making Commercial Mixtures of Hydrogen and Carbon Monoxide. United States Patent 2,541,657, Feb. 13, 1951; appl. filed Mar. 7, 1947, Serial No. 733,176; 4 claims (Cl. 48-196).

To obtain an increased amount of CO from a normally gaseous hydrocarbon, such as CH_4, without causing a corresponding increase in the H₂ content, the following process is used. In one reaction zone, CH₄ is reformed to CO and H₂. In another zone, CH₄ is oxidized to CO₂ and steam. The steam is removed from a portion of the CO₂ and steam mixture, and the CO₂ is reduced to CO, which is recovered separately from the previously mentioned CO and H₂. This gives an added amount of CO to be used in obtaining desired ratios of H₂ : CO mixtures. 5 United States patents cited.
