        Promoting action of Th, Al, U, and Mn oxides on the activity of Co and Ni catalysts mainly is due to their preventing the sintering of the reduced Co and Ni at the higher reduction temperature.  Formation of solid paraffin, which occurs when the synthesis is carried out under pressure, can be ascribed in part to raising the catalyst temperature by the heat of reaction.
