      Theories of hydrocarbon formation are discussed critically; the carbide theory of Fischer and Tropsch is believed most satisfactorily confirmed by experimental findings.  Hydrocarbons higher than CH₄ are obtainable from CO₂-H₂ mixtures only when the intermediate reduction to CO takes place.  These are also obtained when HCOOH and MeOH are passed over Cu-Ni catalyst.  Catalytic formation of paraffins of high melting point and molecular weight, composition, and characteristics of synthesis products, and their behavior as motor and diesel fuels have been investigated.  Bibliography.
