        Production of motor fuels by various processes of carbonization and by solvent extraction and hydrogenation is briefly described.  The author then deals in greater detail with the processes for making Fischer-Tropsch synthesis gas (Koppers, Pintsch-Hillebrand, Wintershall-Schmalfeldt, Didier-Bubiag, Lurgi, and the reforming of waste synthesis gases either by cracking or by partial combustion).  The paper concludes with a discussion of the Fischer-Tropsch process, with particular reference to the products and their treatment by dehydrogenation and polymerization along the lines adopted in the oil industry.
