    摘要: Process for catalytic dehydrogenation of a mixture of light paraffins including passing accelerated catalyst with an acceleration gas into a mixing zone for contact with mixed paraffin feedstock, passing the feedstock/catalyst into a reaction zone, separating the effluent from the spent catalyst solids, quenching the effluent and separating and recycling at least a portion of the unreacted light feedstock for use as an acceleration gas to accelerate the fresh catalyst wherein the kinetic residence time from contact of the catalyst and feedstock to quench is between 0.1 and 2.0 seconds.
