1873. TSUNEOKA, S., AND NISHIO, A. Benzine Synthesis From Carbon Monoxide and Hydrogen at Ordinary Pressure. XXXVII. Volume Velocity of the Gas. Jour. Soc. Chem. Ind. (Japan), vol. 41, suppl., 1938, pp. 11-16; Sci. Papers Inst. Phys. Chem. Research (Tokyo), vol. 34, 1937, pp. 83-98; Chem. Abs., vol. 32, 1938, p. 3592.

For given amounts of catalyst and fixed layer lengths, the yield of benzine decreases if the velocity of the current of gas is increased. With a fixed-gas volume velocity and catalyst-layer length, the yield of benzine obtained during an increasing velocity of the current of gas after it once reaches a maximum decreases gradually. The amount of unsaturation has a tendency to rise with the larger values of gas-volume velocity. In a reaction tube of 20 mm. width, with a constant gas-volume velocity (500), the unsaturation increases as the velocity of the current of a gas becomes larger. If the volume velocity of the gas is not large, the rate of production of CO₂ tends to increase with the amount of catalyst.
