      1108.  HUBER, H. E., Jr.  (Standard Oil Co. of Indiana).  Hydrocarbon Synthesis.  United States Patent 2,417,164, Mar. 11, 1947: appl. Filed Nov. 23, 1944, Serial No. 564,811: 4 claims (Cl. 260-449.6).  Chem. Ans., Vol. 41, 1947. p. 3603.

Gives a 2 stage process for production of gasoline hydrocarbons from CO and H₂.  A fluidized Fe catalyst is used in the 1^st stage, and a precipitated Co or Ni type, either fluidized or in stationary bed, is used in the 2d stage.  The synthesis gas charge consists of H₂ and CO in a ratio of 1:1 or 1.8:1.  The proper ratio in the feed to the Fe system is necessary to produce the ideal feed for the Co system or 2:1 or 2.2:1 H₂:CO ratio.  The temperature range for the Fe system is 450°-650° F., pressure 100-350 p. s. i. and space velocity 1,000-10,000 vol. Of gas per hr. per vol. Of space occupied by the dense catalyst phase of the reactor.  The temperature range for the Co is 340°-500° F., preferably <420° F., pressure not >50 p. s. i. and preferably atmospheric, space velocity 50-1,500 vol. Of gas per hr. per vol. Of space occupied by the dense catalyst phase.  The reaction in the 1^st stage is 3nH₂+3nCO→2(CH₂)_n+nH₂O+nCO₂, and for the 2d stage, 2nH₂+nCO→(CH₂)_n+nH₂O.  Total reaction products are removed after each stage.  3 United States patents cited.
