                 Because of the limited supply of Co and Ni in China, increased use must be made of Fe catalysts in industrial processes.  In preparing the catalyst, Fe plus varying amounts of Cu as promoter are dissolved in HNO₃, mixed with starch, kieselguhr, and K₂CO₃ and ignited.  Water gas is passed through the reactor at a rate of 2 1. per hr. and the yield measured in terms of ml. per m.³ of gas.  Each run was continued for 20 days or more, and the products were examined at 24-hr. intervals.  Maximum results are obtained when about 0.5% of K₂CO₃ is present and when the Fe:Cu ratio is 5:1.  Satisfactory yields are obtained at a reaction temperature of 240°.  The activity of the Fe catalysts was long lived.  The kogasins produced gave on distillation good yields of light oil as well as paraffin.
