Abstract

Unsaturated hydrocarbons are produced by the pyrolysis of liquid hydrocarbons by spreading out the liquid hydrocarbon on the inner wall of a cylindrical or part conical chamber by means of a propellant gas introduced tangentially at 50-300 metres/sec. and at a temperature which does not effect appreciable cracking and passing a hot gas axially through the chamber cocurrently with the liquid hydrocarbon feed to effect pyrolysis. The liquid hydrocarbon may be a gasoline boiling in the range 80-220 DEG C., a middle oil boiling in the range 90-350 DEG C. or a higher boiling petroleum fraction and is introduced tangentially or radially. The propellant gas may be steam at 200-400 DEG C. mixed, if desired, with nitrogen or carbon dioxide, or hydrogen or carbon monoxide together with oxygen to provide the desired temperature, in amounts of 10-80% by volume of the steam, the total gas amounting to 0.2-1 kg. per kg. of hydrocarbon. The cracking gas may be hot steam, nitrogen or carbon dioxide or a combustion product at 800-1500 DEG C. The pressure may be 2-30 excess atmospheres. The product which may contain ethylene, propylene or acetylene is quenched with water or by decompression.
