Abstract
The rate at which an oxygen-containing gas stream is admixed with hydrocarbons and hydrogen upstream of a catalytic hydrogen oxidation zone is controlled on the basis of temperature differentials across the oxidation zone and an upstream catalytic dehydrogenation zone. This control overrides the normal control mode based upon the outlet temperature of the oxidation zone effluent stream, which is the inlet temperature to a subsequent bed of hydrocarbon conversion catalyst. The control method can be used to apply oxidative reheat technology to a variety of processes.
