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.
