3771.     ZWERGAL, A.  [Role of Hydrocarbons in the Production of Synthetic Fats by Oxidation in Germany.]  Kolloid-Ztschr., vol. 112, 1949, pp. 168-182; Chem. Zentralb., 1950, I, p. 238.

        Describes Fischer-Tropsch process and discusses Fe catalyst, its preparation and reduction, the synthesis gas, and the effect of certain variables, such as space velocity and heat of reaction upon the synthesis.  Normal, medium, and high pressures and the Synol and Oxo processes are considered.  The physiological effect of the isocompounds is explained.  It is shown how the synthesis of fuels can be suppressed in favor of the synthesis of solid paraffins.
