摘要
A process for the dehydrogenation of paraffins is presented. The process utilizes a rapid recycling of dehydrogenation catalyst between the dehydrogenation reactor and the catalyst regeneration unit. The process comprises preheating a combined hydrogen and paraffin hydrocarbon feedstream and passing the combined stream to a dehydrogenation reactor. The hydrocarbon feedstream and the catalyst pass through the reactor at a rate to limit the average residence time of the catalyst in the reactor. The catalyst is cycled to a regeneration unit and passed through the regeneration unit to limit the average residence time of the catalyst in the regeneration unit.
