2173. ------. [MAYLAND, B. J.] (Phillips Petroleum Co.). Fluidized Iron Oxide-Natural Gas Process for Manufacturing Synthesis Gas. United States Patent 2,628,161, Feb. 10, 1953; appl. filed Sept. 17, 1948, Serial No. 49,826; 2 claims (Cl. 48-196). Chem. Abs., vol. 47, 1953, p. 5099.

A gaseous oxidant, such as steam, CO₂ and/or O₂, is introduced to a fluidized reaction zone in which CO and H₂ are being produced by oxidation of CH₄ with Fe oxide. The oxidant gives more efficient consumption of the CH₄. Another advantage is the addition of heat to the reaction zone to reduce the amount of heat necessarily supplied by the Fe oxide or other solid heat carrier. 3 United States patents cited.
