A radial flow reactor design which allows the maintenance of a temperature profile along the height of a catalyst bed which descends through the reactor by gravity flow. Two feed inlet conduits are provided on the inlet side of the annular catalyst bed, with the inlets being divided by a porous flow control and distribution means. The inlet streams have different temperatures and the distribution means produces a changing admixture rate between the two streams along the bed. A preferred form of the distribution means is an open-topped cone located within the centerpipe of the reactor.

A moving bed radial reactor which comprises: (a) an enclosed outer vessel comprising a cylindrical outer wall; (b) an annular form catalyst bed confined within a catalyst retaining system comprising an inner catalyst retention screen and an outer catalyst retention means; (c) a first fluid outlet means communicating with a first fluid transfer volume located between the outer catalyst retention means and the outer wall of the vessel; (d) means to maintain a temperature profile along the height of the catalyst bed comprising: (i) a perforated wall which substantially divides a cylindrical second fluid transfer volume located within the inner catalyst retention screen into a first fluid receiving volume and a second fluid receiving volume, and provides, at one end thereof, for contact of the catalyst with a first fluid only and, at the other end thereof, provides for contact of the catalyst with a second fluid only and between said ends provides for contact of the catalyst with a controlled mixture of said first fluid and said second fluid; (ii) a first fluid inlet conduit for entry of said first fluid to said reactor having a set temperature communicating with the first fluid receiving volume; (iii) a second fluid inlet conduit for entry of said second fluid to said reactor having a set temperature different from the temperature of said first fluid communicating with the second fluid receiving volume; and, (e) means to transfer catalyst downward by gravity flow through the catalyst retaining system.
