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.
