135. -----. (Standard Oil Development Co.) Hydrocarbon Synthesis. United States Patent 2,475,214, July 5, 1949: appl. filed Oct. 12, 1944, Serial No. 558,338; 1 Claim (Cl. 260-449.6). Chem. Abs., vol 43, 1949. p. 8120.

 After formation by the usual methods, synthesis gas is cooled at 400º -600º F., the temperature of the synthesis reaction.  The hot synthesis gas may be cooled by direct introduction of an H₂O Spray, forming steam.  The H₂O may be injected into the transfer line connecting the synthesis gas generator with the synthesis reactor.  The total concentration of steam finally present in the gaseous mixture is 25%-100% by volume by volume of the amount of CO plus H₂ present in the mixture.  The gases are fed to a reactor containing powdered CO catalyst (200- to400-mesh).  The space velocity is 1.5--3 ft. per second, and a dense turbulent suspension of catalyst, having a density of 10-30 lb.  per cu. ft., is maintained.  Normally liquid hydrocarbons are formed.  1 foreign and 7 United States patents cited.
