IMPROVED HORIZONTAL RADIAL FLOW REACTOR

Abstract

A horizontal radial-flow reactor (1) comprising a horizontal reaction vessel (2) including an annular cylindrical reaction space (3) configured to contain a catalyst (4) for processing a gaseous flow, the reactor (1) comprising a plurality of gas permeable scallops (6) which surround said reaction space (3) and are arranged to distribute or collect said gaseous flow into or from said reaction space (3), wherein said gas permeable scallops (6) are distributed circumferentially around an outer boundary of the reaction space (3), including a gap in the array of scallops where shrinkage of the catalyst can occur while maintaining the symmetry of the catalyst distribution and a port in communication with said gap to load or unload a catalyst into or from said reaction space (3).
