ABSTRACT:
A process for the catalytic dehydrogenation of a dehydrogenatable C.sub.2 -plus feed hydrocarbon which comprises the steps of: (a) passing a feed stream comprising the C.sub.2 -plus feed hydrocarbon into a dehydrogenation zone and through at least one bed of dehydrogenation catalyst maintained at dehydrogenation conditions and producing a dehydrogenation zone effluent stream comprising hydrogen, the C.sub.2 -plus feed hydrocarbon and a C.sub.2 -plus product hydrocarbon; (b) forming an oxidation catalyst bed feed stream by admixing an oxygen-containing stream with the dehydrogenation zone effluent stream; (c) passing the oxidation catalyst bed feed stream through a bed of hydrogen selective oxidation catalyst maintained at selective oxidation conditions and producing an oxidation zone effluent stream having a reduced concentration of hydrogen; and (d) recovering the product hydrocarbon from the oxidation zone effluent stream without contacting the oxidation zone effluent stream with dehydrogenation catalyst.
