Fischer-Tropsch process for synthesizing hydrocarbons from CO and H2 in presence of a Co-Th-kieselguhr catalyst is described. The composition of the products depends on the H2:CO ratio, the proportion of gases to catalyst, and the pressure. The yields of gaseous, liquid, and solid products at various pressures are tabulated. Waxes formed during the synthesis and impurities in the gases, especially S, reduce the activity of the catalyst. The synthesizing plant is described briefly, and the application of the products is discussed, with special reference to motor fuel and lubricating oil.
