        Development is announced of the Fischer-Tropsch process, which makes possible the production of gasoline from natural gas with a yield of 80% and an octane No. of 75 motor (83 research) for about $0.05 per gal., based on natural gas at $0.05 per 1,000 ft.³ and a plant depreciation of 10%. The new method is said to overcome successfully the problem of heat dissipation and accurate temperature control.  Prewar European yields by the then existing methods were 30-40% of approximately 25 octane No. gasoline.  The Kellogg Co. is prepared to build hydrocarbon synthesis plants using the process.  Recently sintered Fe catalysts have been introduced, resulting in a product of a mixture of varying molecular weight hydrocarbons in which isoparaffins and even naphthenic and aromatic mixtures are the main constituents instead of the predominant normal paraffins formed with the Co and Ni catalysts.
