Vapor-Phase Treatment of Combined Gasoline and Water Phases of Synthesis Product With a Basic Compound. United States Patent 2,591,699, Apr. 8, 1952; appl. filed Nov. 14, 1949, Serial No. 127,201; 9 claims (Cl. 260-450). Product obtained by the catalytic conversion of CO and H2 to liquid fuel is separated at 200°-400° F. and 150-500 p. s. i. into a gas phase, a H2O phase, and an oil phase, the gas phase being recycled to the reaction zone where the CO and H2 are converted into liquid hydrocarbons. The oil phase is separated into a gasoline fraction and a gas-oil fraction, the former being combined with the H2O phase. The composite thus formed is vaporized and treated at about 500° F. with a basic compound such as Na2CO3. This has the effect in the hydrolyzing the H2O- and oiil-soluble esters boiling in the gasoline range to alcohols and acids and of decarboxylating the H2O- and oil-soluble acids boiling in the gasoline range either to hydrocarbons or ketones. After the treatment with the basic compound, the composite is cooled and separated into a gaseous fraction, a H2O phase, and a gasoline phase. The gaseous fraction is recycled to the reaction zone, while the alcohols and ketones are separately removed from the H2O and the gasoline phases. HEUNICKE, W. See abs. 3890. |
