    Abstract: Process for the production of an olefin comprising partially combusting in a reaction zone a mixture of a hydrocarbon and an oxygen-containing gas in the presence of a catalyst which is capable of supporting combustion beyond the fuel rich limit of flammability to produce the olefin. The superficial feed velocity of the mixture is at least 250 cm s−1 at standard temperature and operating pressure, with the proviso that where the catalyst is an unsupported catalyst, the superficial feed velocity of the mixture is at least 300 cm s−1 at standard temperature and operating pressure. The process is carried out at a pressure of at least 1.3 bara and the reaction zone is not externally heated.

    Abstract: Process for the production of olefins such as ethylene from a hydrocarbon such as ethane. The process involves passing a mixture of the hydrocarbon and an oxagen-containing gas through a catalyst zone which is capable of supporting combustion beyond the fuel rich limit of flammability to produce the olefin. The catalyst zone comprises at least a first catalyst bed and a second catalyst bed. The second catalyst bed is located downstream of the first catalyst bed, is of a different composition to the first catalyst bed and comprises at least one metal selected from the group consisting of Mo, W, and groups IB, IIB, IIIB, IVB, VB, VIIB and VIII of the Periodic Table. Suitably, the first catalyst bed comprises platinum and the second catalyst bed comprises tin- or copper-promoted nickel, cobalt or iridium catalyst or a copper-only catalyst.
