        Influence of K₂CO₃, Cu, ThO₂, Al₂O₃ and MnO on the activity of a Co catalyst was studied by the method described above.  The decomposition of CO with separation of C is not evident when ThO₂ or Cu is added to the Co catalyst, while the addition of K₂CO₃ decreases it.  ThO₂ and Cu to a less degree increase the activity of Co toward the reduction of CO and the formation of hydrocarbons.  Al₂O₃ and MnO are detrimental to the activity of Co.
