        In order to synthesize predominantly C₄ hydrocarbons, a synthesis gas composed of equal parts of CO and H₂ was passed at temperatures varying from 242°-299° over an Fe catalyst containing Cu, 25; Mn, 2; kieselguhr, 125; H₃BO₃, 20; K₂CO₃, 3%.  Increase in temperature resulted in a decrease in CH₄ formation and a decrease in reaction velocity.  The maximum yield of gasoline was reached at 250°, while the yield of C₄ hydrocarbons increased up to 270° and remained virtually constant above this temperature.  Operation at 251°-253° with varying space velocities indicated that a space velocity of 180-200 represents the optimum for C₄ hydrocarbon production.
