593. ------. [EASTMAN, D., AN GAUCHER, L. P.] (The Texas Co.). Manufacture of Synthesis Gas. United States Patent 2,582,938, Jan. 15, 1952; appl. filed Oct. 21, 1950. Serial No. 191,446; 11 claims (Cl. 48-196). Chem. Abs., vol. 46, 1952, p. 3244.

Synthesis gas consisting essentially of CO and H₂ and substantially free from solid C is produced by reacting a hydrocarbon (natural or coke oven gas, liquid hydrocarbon) with a gas containing at least 40 vol. % O₂. The reactants are continuously passed into a closed reaction zone free from packing and catalyst and having an internal surface area no > about 1.5 times the area of a sphere of equal volume. The ratio of total O₂ : C in the feed gas is about 1.0-1.5. The hydrocarbon gas is charged at a rate of about 1,000-3,000 cu. ft. per hr. per cu. ft. of reaction space, the temperature in the reaction zone being maintained at about 2,300º-3,000º F. and the pressure, 200-500 p.s.i.g. It is desirable to reduce the temperature of the effluent stream of gas from the reaction zone from about 2,600º F. to 1,000º-5,000º F. in not > 1 sec. So as to avoid undesired side reactions. The effluent gas consists essentially of CO and H₂ substantially free from uncombined O₂ and C and with CH₄ content of 0.0-0.5 mol.%.
