Abstract: A process for the production of olefins from a hydrocarbon comprising the steps of: a) providing a first feed stream comprising a gaseous fuel and an oxygen-containing gas; b) contacting the first feed stream with a first catalyst under conditions so as to produce a product stream and unreacted oxygen; c) providing a second feed stream of hydrocarbon feedstock; and d) contacting the second feed stream, the product stream of step b) and the unreacted oxygen step b) with a second catalyst which is capable of supporting oxidation, thereby consuming at least a part of the unreacted oxygen to produce an olefin product.
