1. A process for changing overall catalytic activity in a fixed bed, radial flow reforming reactor, the process comprising:
forming a first annular zone in the radial flow reforming reactor, the first annular zone comprising a first solid particle material having a first catalytic activity for reforming hydrocarbons;
forming a second annular zone in the radial flow reforming reactor, the second annular zone comprising a second solid particle material having a second catalytic activity for reforming hydrocarbons, the second catalytic activity different than the first catalytic activity; and,
providing a divider between the first and second annular zones;
wherein the first and second annular zones define a flow path for a stream of hydrocarbons, and
wherein the flow path passes from the first annular zone to the second annular zone, and
wherein the divider is removed before operating the fixed bed, radial flow reforming reactor.
