    Abstract: The production of olefins or producer gas is effected by vaporizing a vaporizable liquid hydrocarbon mixing it with oxygen or air and steam or carbon dioxide, and introducing it at atmospheric or increased pressure through a burner into a reaction chamber and simultaneously introducing a non-vaporizable liquid hydrocarbon through an atomizing jet in the same burner into the mixture of vaporized hydrocarbon and gases. Vaporizable hydrocarbons are hydrocarbons which can be vaporized without leaving a residue, e.g. light gasoline, liquefied gases and petroleum distillates; non-vaporizable hydrocarbons are those which cannot be vaporized without leaving a residue, e.g. crude oils, residue oils and oils containing compounds forming non-volatile resins. The vaporizable and non-vaporizable liquids may be obtained from a single feed by passing into a vaporizer, the nonvaporizable portion being recovered from the sump. Suitable conditions are 600 DEG -2,000 DEG C. and up to 30 atmospheres. In the drawing, vaporizable hydrocarbon enters through vaporizer 1, and gases by line 3 and after mixing flow through the annular space 4 of the burner 2. Liquid hydrocarbon is preheated before spraying through jet 7 which is drawn back to prevent wetting of the reaction chamber walls. The whole mixture is ignited. The reaction chamber may be empty or filled with coke or other inert solid or catalyst.
