When precipitated with Fe+25% Cu+2% Mn+125% kieselguhr+2% KOH catalyst or when Al₂O₃ was added before precipitation. Al₂O₃ decreased the yield of benzine at 250° from gas containing approximately equal amounts of CO and H₂. When 1-3% Al₂O₃ was added (based on Fe present) after precipitation of the catalyst, the benzine yield was increased (94 cm.³ per m.³ with 3% Al₂O₃). Addition of the following Al compounds (2-5% with respect to Fe present) to the above catalyst resulted in decreasing yields of benzine in the order shown: AlPO₄>Al acetate >Al silicate >Al (OH)₃ >”Al₂(CO₃)₃.” The yield of benzine was O when Al₂(SO₄)₃ of AlCl₃ was added to the catalyst. Acid-clay (containing approximately 15% Al₂O₃) added to the above catalyst in quantities up to 25% (based on Fe present) increased the benzine yield, but when the acid clay was substituted for a portion of the kieselguhr of the catalyst, inferior yields were obtained. Coprecipitation of Ag (3-30%, based on Fe content) with the above catalyst or addition of 3-10% Ag₂O to the catalyst resulted in unchanged or diminished yields of benzine. Substitution of the Cu of the catalyst by 10, 20 or 30% Ag (based on Fe present) resulted in very inferior yields of benzine and the formation of some paraffin wax. Precipitation of 2-5% (based on Fe present) of Ba, Ca, Cd, Bi, Pb, Sn or W with the above catalyst resulted in inferior yields of benzine, Bi, Pb and W giving especially low benzine yields.
