Zusammenfassung:Processes for catalytic dehydrogenation of paraffin stream is disclosed. The process includes passing a first portion of the paraffin-containing feedstream through a select catalytic reactor in a plurality of catalytic reactors. An internal differential pressure is measured in the select catalytic reactor. A second portion of the paraffin-containing feed stream is bypassed around the select catalytic reactor when the measured internal differential pressure is above a predetermined limit of the internal differential pressure. The bypassed second portion is passed to at least one other catalytic reactor in the plurality of reactors located downstream of the select catalytic reactor being bypassed.
