Abstract: Acetylene is obtained by thermal cracking of liquid hydrocarbons in the presence of insufficient oxygen for complete combustion by reacting part of the liquid product containing carbon black with oxygen by burning in a free space and introducing into the combustion products lateral, penetrating jets first of hydrocarbon to be cracked in an amount of 1-3 kg. per cubic metre (S.T.P.) of oxygen and then, as quenching fluid, liquid product containing carbon black in an amount to reduce the temperature below 500 DEG C. The flame direction is preferably upward and the reactor walls may be washed with liquid cracked product. The amount of liquid product, boiling above 85 DEG C., recycled to the burner may be 30-150% of the hydrocarbons to be cracked. The process may be effected at 1-20 atmospheres, the combustion products being at 1200-2800 DEG C. before mixing with the hydrocarbon feed and 800-1600 DEG C. after. Diluent gases, e.g. steam or carbon dioxide, may be introduced at any point as desired. In an example, crude petroleum oil is cracked.

Abstract: In the production of olefins by the autothermal cracking of hydrocarbon oils at 630 DEG -850 DEG C. in the presence of a fluidized bed of coke particles and sufficient oxygen to supply the heat of reaction, the product boiling above 250 DEG C. being recycled, the feed has less than 2,5% Conradson carbon and is mixed with at least part of the oxygen and introduced laterally into the fluidized bed which is fluidized from below by a fluidizing agent which may contain further oxygen. The feed is preferably a crude petroleum, e.g. of Bahia or Sahara origin and is mixed with 20-100% of the oxygen and also steam if desired. The recycle is introduced with the feed or separately and may also be mixed with oxygen in the latter case. Mixing is preferably effected at the point of injection, e.g. using a nozzle having an annular feed for oxygen and an inner feed for the oil. The nozzle or nozzles may be between 20 cms. above the bottom to 1m. below the top of the fluidized bed.
