<p>An improved process for dehydrogenation of detergent range normal paraffins contained in a hydrocarbon mixture to produce monoolefins is described. Improvements are obtained by operating over an entire catalyst operating cycle at an average added hydrogen to detergent range hydrocarbon ratio of from about .5 to about 1.9. The improved process is operated in a substantially adiabatic, plug flow reactor at a suitable catalyst bed inlet temperature not greater than about 450 DEG C. The process provides improved tolerance for initial excess catalyst bed activity, allowing desirable catalyst operating cycle lengths to be obtained with more favorable operating conditions.</p> |
