3956.  WIRTH, G., WENSZEL, W., SABEL, F., AND LAUDENKLOS, H. hydrocarbons From Carbon Monoxide and Hydrogen. United States Patent 2,338,475, Jan. 4, 1944. Chem. Abs., vol. 38, 1944, p. 3801.

In the production of hydrocarbons containing more than 1 C atom in the molecule, with removal of excess reaction heat by indirect heat exchange with a cooling medium coming into contact with the walls of the reaction space, the gas, comprising CO and H2, is passed through the reaction space with a linear velocity of flow of at least about 0.6 m. per sec., and there is maintained a ratio of the space velocity of the gas to the height of the catalyst layer, expressed in meters, of not greater than about 100. Operation under these conditions serves to produce a benzine relatively stable to knocking.
