Abstract
A process is presented for the dehydrogenation of hydrocarbons in a radial flow reactor. The process includes the continuous feeding of catalyst into the reactor and the continuous withdrawal of catalyst from the reactor, where the catalyst is modified to increase the increased density. The catalyst is a layered structure with a dense core and an active catalytic outer layer.
