Abstract

A process and apparatus for the dehydrogenation of paraffins is presented. The process utilizes a reactor that includes a slower flow of catalyst through the reactor with a counter current flow of gas through the catalyst bed. The catalyst is regenerated and distributed over the top of the catalyst bed and travels through the bed with the aid of reactor internals to limit backmixing of the catalyst.
