PATENTS 2786 -----[ROBERTS, G., JR.] (M.W. Kellogg Co) Preparing Mixtures of Carbon Monoxide and Hydrogen Suitable for Use in Catalytic Synthesis. United States Patent 2,185,989, Jan. 2, 1940; appl. filed Aug. 19, 1938, Serial No. 225,755; 6 claims (Cl. 23-212). Chem. Abs., vol. 34, 1940 p. 2862. Describes arrangement of apparatus and a method of preparing a mixture of CO and H2 for catalytic synthesis, including the steps of desulfurizing CH4, to remove objectionable S compounds, subjecting a CO2 bearing gas to absorption by an absorption menstruum selective to CO2 in an absorption zone, stripping the absorbed CO2 from the absorption menstruum by means of the CH4 removed from the desulfurizing zone and thereby forming a mixture of CO2 and CH4, generating the desired synthesis gas comprising CO and H2 by heating the mixture of CO2 and CH4 in a synthesis-gas generating zone at temperatures above 815° in the presence of a catalyst.. |
