Catalysts consisting mainly of metals of the Fe group, are produced from the metals themselves rather than from the oxides. The metals are mixed with activating substances and then treated and reduced with H₂-containing H₂O vapors at temperatures > 600°. Example: 2,000 gm. of powdered Fe obtained by the decomposition of Fe carbonyl are suspended in a solution of 10 gm. of Ag nitrate in 1.5 1. of H₂O. After the Ag-impregnated Fe is sucked off, washed, and dried 10 gm. of Ti oxide, 20 gm. Ca oxide, and 40 gm. dextrin are added, and the mixture is pressed into pellets and treated for 7 hr. at 800°-850° with H₂O vapor-H₂ mixture obtained by passing steam over red-hot Fe shavings. After reduction with H₂ at 650° this catalyst yields, per m.³ of synthesis gas (1 : 2= CO + H₂) at 100 atm. and 320°, 75 cc. of hydrocarbon oils, and 225 cc. H₂O with 31% alcohols.
