ABSTRACT:
Hydrocarbons are catalytically dehydrogenated in a reaction zone comprising at least two separate beds of dehydrogenation catalyst. The reactants are reheated and hydrogen is consumed through use of an intermediate bed of hydrogen selective oxidation catalyst. The amount of hydrogen consumed in the combustion step is increased by cooling the effluent of the first dehydrogenation catalyst bed by direct or indirect heat exchange.
