2776. -----. [RIBLETT, E. W.] (Hydrocarbon Research, Inc.).  Producing Hydrocarbons by the Catalytic Reduction of Carbon Monoxide by Hydrogen.  United States Patent 2,525,827. Oct. 17, 1950; appl. filed July 19, 1947, Serial No. 762,020; 6 claims (Cl. 260-449.6). Chem. Abs., vol. 45, 1951, p. 334.

        Stripping gas, after removing absorbed hydrocarbons from the synthesis catalyst, is passed through a conventional plant for recovering natural gasoline, and the residual gases are converted by partial oxidation  to synthesis gas to be used in the reaction zone.  Catalyst is removed and stripped in a separate zone with additional wet natural gas, which is treated for recovery of liquid products and then used to supplement the synthesis gas feed.  7 United States patents cited.
