1755. ------. [JAEGAR, A. O.] (Selden Co.). Reduction of Carbon Monoxide. United States Patent 1,741,306, Dec. 31, 1929; appl. filed Nov. 8, 1927, Serial No. 232,003. Chem. Abs., vol. 24, 1930, p. 1125.

CO or a gas containing CO is caused to react with a H₂ containing gas in successive stages to form CH₂O, MeOH, and then CH₄, without isolating intermediate products formed, and at least 1 of the 1^st 2 stages of the reaction is effected in the presence of mild reduction catalysts such as Cu, Mn, Cd, Zn, Pb, Sn, Mg, Ag, Au, or Pt associated with oxidation catalysts such as compounds of Cr, V, Ti, Mo, W, Ce, Th, U, or Zr, both of which are incorporated in porous carriers such as pumice or kieselguhr of not more than slight catalytic activity; the stage producing CH₄ from MeOH is effected in the presence of strong reduction catalysts such as Fe, Ni, Co, or Pd.
