ABSTRACT:
In a steam active catalytic process employing a fixed catalyst bed for the dehydrogenation of alkanes to alkenes wherein reaction temperatures above about 500.degree. C. (932.degree. F.) must be maintained for commercially feasible conversions, the decline in catalyst activity druing a production period is slowed by maintaining a substantially constant temperature for the reaction effluent while allowing the average temperature of the fixed catalyst bed to rise during a production period.
