733. FRANKENBURG, W. G., AND LAYING, E. T. (Hydrocarbon Research, Inc.). Hydrocarbon Synthesis. United States Patent 2,600,399, June 17, 1952: appl. filed July 11, 1947, Serial No. 760,498; 12 claims (Cl. 260-449.6). Chem. Abs., vol. 46. 1952. p. 8352.

Synthesis of hydrocarbons and oxygenated hydrocarbons by the reaction of H₂, CO, and CO₂ in the presence of an Fe synthesis catalyst at about 500º-750º F. and superatmospheric pressure with the consumption of at least 80% of the CO supplied to form the desired products is improved by use of a reactant gas containing >about 15 mole % CO and <about 2 mole % H₂O, based on the total moles of CO, H₂, and CO₂ present. The flow of gas is in conformance with the equation: log_e(K+50)=-0.1548.4-0.1075G-0.001512T+loge279.8, where K is <15. A is the ratio of moles H to moles CO in the feed gas, G is the ratio of moles CO₂ to moles CO in the feed gas, and T is the absolute temperature in ^eK. By this process the production of CO₂ is limited to <15%, and CO₂ can even be consumed in the reaction.
