1592. IVANOVSKIĬ, F. P., BRAUDE, G. E., AND PANINA, A. M. [New Catalysts for the Conversion of Carbon Monoxide.] Jour. Chem. Ind. (U.S.S.R.), vol. 10, No. 2, 1934, pp. 37-44; Chem. Abs., vol. 28, 1934, p. 3845.
Fe catalysts should be heated for 2 hr. at 700° before use to give them the greatest stability. Co catalysts are very active but are mechanically weak. Addition of MgO strengthens them but lowers their activity. Siderite is a good catalyst, but it loses its activity on prolonged use. The loss may be prevented by addition of 0.7% by wt. of K2Cr2O; to siderite that has been heated for 6 hr. at 500°-525°. Such a catalyst gives 94-96% conversion. Addition of too much K2Cr2O7 weakens the catalyst. H2S lowers its activity. Titanomagnetite, Fe chromite, and bauxite are unsatisfactory as catalysts.
