ABSTRACT:
A fixed bed, dual-zone radial flow catalytic reactor is disclosed. In particular, the catalyst bed configuration includes a first freeboard outwardly radial flow catalyst zone in series with a second inwardly radial flow zone separated by an interconnecting substantially impermeable catalyst chute to accommodate catalyst settling while preventing hot spots and/or fluidization in the freeboard area. A gas distributor divides the freeboard zone into segments including a bypass segment and one or more catalyst segments. The radial flow of gas through each segment is essentially unaffected by the level of catalyst so that the flow pattern is not adversely affected by catalyst setting in the freeboard zone.
