3149.----- [RUHRCHEMIE, A. G.] [Production of Hydrocarbons by Catalytic Hydrogenation of Carbon Monoxide.] French Patent 836,273, Jan. 13, 1939. Chem. Abs., vol. 33, 1939, p. 55633.

Synthesis is effected in apparatus comprising cooling tubes and plates of good heat conductivity. The pressure in the reaction chamber is maintained substantially the same as that of the cooling fluid passing through the cooling tubes. A mixture of 21 part of Co to 2 parts of H₂ is passed up through a reaction chamber containing a catalyst. ho H₂O at 1186° under a pressure of 11 atm. is passed through the cooling 187°. The pressure of the gases in the reaction chamber is maintained at 11 atm. On leaving the chamber the gas is cooled and H₂O, spirits, and oils are condensed. The residual gas is then treated with active C to remove hydrocarbons similar to gasoline and lower boiling spirits. A Co-Th catalyst may be used.
