      General review of present developments in the conversion of oils to benzine by cracking, by heating under pressure with H₂, and by catalytic decomposition and of attempts to synthesize hydrocarbons from H₂ and CO.  Describes a new process developed by Dal Prato, consisting of the catalytic decomposition of complex molecules of the heavy hydrocarbons to benzine and gases and the catalytic synthesis of these gases to benzine.  Process does not include hydrogenation.
