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.
