2712. ------. [POTTS, H. E.] (International Hydrocarbon Synthesis Co.). Process and Apparatus for the Production of Hydrocarbons by Reduction of Carbon Monoxide With Hydrogen. British Patent 567,609, Feb. 23, 1945; appl. filed May 12, 1941. Chem. Abs., vol. 41, 1947, p. 2559.

Gives process and apparatus for the production of hydrocarbons with more than 1 C atom in which the distance in the vertical tubes is at least 5 m. between the inlet and outlet openings. The tubes are surrounded by a boiling cooling medium. H₂O, diphenyl, glycerin, paraffin oil, and tricresyl phosphate may be used as the cooling medium. The invention allows the gases to be passed through the catalyst tubes at a higher linear velocity, thereby effecting a better transmission of the reaction heat to the cooling wall.
