Abstract
In an endothermic steam active catalytic process employing a fixed catalyst bed in a fuel fired reactor for the dehydrogenation of alkanes to alkenes, wherein a reaction temperature above about 500.degree. C. (932.degree. F.) is maintained for commercially feasible conversions, and wherein catalyst activity declines during a production period, apparatus for control of a process temperature so as to compensate for catalyst activity decline includes a temperature sensor mounted in the reaction effluent stream in combination with a temperature controller which automatically adjusts the quantity of fuel supplied to the fired reactor.
