Activity and Stability of Fe-Cu-ThO₂-K₂CO₃ Catalyst in the Synthesis of Liquid Hydrocarbons From CO-H₂ Mixture as Influenced by Composition of the Catalyst and the Nature of the Carrier. Bull. Acad. Sci. U.R.S.S., Classe Sci. Chim., 1943, pp. 305-311 (English summary); U.O.P. Co. Survey Foreign Petroleum Literature Transl. 468; Chem. Abs., vol. 38, 1944, p. 5648.

18 catalysts of composition Fe-Cu-ThO₂-K₂CO₃-carrier were examined in the synthesis of liquid hydrocarbons from 1 CO : 2H₂ mixture. The catalyst Fe 100 : Cu 25 : K₂CO₃ 2 : kieselguhr 125 shows a sharp optimum for ThO₂ content at 1%. Slight maximum in efficiency is found at 2% K₂CO₃ in Fe 100 : Cu 25 : ThO₂-kieselguhr catalyst. In this catalyst, the best results were obtained with the carrier of Insen diatomite and marshallite, the latter support being somewhat more stable. The results contradict the view of catalyst support as an inert mass. The Fe catalysts investigated showed poor stability, which was not improved with variations of ThO₂ content.
