    Abstract: In the production of olefins, e.g. ethylene and propylene, by cracking hydrocarbon oils autothermally in the presence of oxygen in a fluidized bed of oil coke there is added batchwise to the coke during the process a small amount e.g. 0.05-6% by weight of the coke of a substance containing phosphoric acid and/or boric acid and/or a salt thereof, e.g. by spraying or injection. Cracking is effected at 630-850 DEG C. and material in the product boiling above 250 DEG C. is recycled. The bed is fluidized with steam and/or carbon dioxide and the oxygen may be mixed with this or at least partly with the oil. Specification 933,301 is referred to.

    Abstract: In the production of acetylene by subjecting hydrocarbons to high temperatures, the hot gas is quenched in a single stage by injecting a hydrocarbon oil boiling above 150 DEG C. in a volume ratio to gas (measured under standard conditions) of at least 1 : 100 without any appreciable cracking of the oil and separating the hot oil containing carbon black from the gas. The oil is preferably an aromatic oil and useful heat is extracted from it before its reuse; the carbon black content is preferably reduced to below 35% by weight e.g. by removing part of the oil and replacing this by fresh oil. The gas is preferably also later washed with an oil boiling in the range 80-450 DEG C. having a specific gravity below 0.95. The examples relate to the partial combustion of gasoline and of methane; reference is also made to heating hydrocarbons by electric discharge and exposure to hot flame gases. Specification 893,504 is referred to.

    Abstract: In the production of acetylene by the partial oxidation of hydrocarbons having molecular weights in the range 60-110, the separately preheated hydrocarbon and oxygen reactants are mixed in a mixer with a residence period below 0.1 second, then passed through a gas distributing block into a reaction chamber, the velocity of the gas mixture immediately before entering the gas distributer being more than 5 metres per second, preferably more than 10 meters per second. Times and speeds relate to conditions at 0 DEG C. and 760 mm. The speed of the gases through the channels of the gas distributer is usually above 20 metres per second. Preferably a hydrogen-containing gas is added to the hydrocarbon, e.g. residual gas from the process. By introducing additional gaseous or liquid hydrocarbon into the reaction zone ethylene is also formed. The process is particularly applicable to the partial oxidation of naphthas, and the preheating temperature may be 600 DEG C.
