International Classification:

B01J 8/02

Abstract:

The invention relates to distributing reactants more evenly across the interior space of a reactor vessel utilizing a distributor at the inlet end that initially directs the flow of reactants through a series of circumferential nozzles. The nozzles are physical spaced such that the first nozzle provides the reactants into the vessel to spread radially and broadly outwardly into the vessel and each successive circumferential nozzle to deliver reactants in a less broadly distribution or dispersion where the interior space is filled with reactants without broadly diverse velocities that may create hot spots within the catalyst bed. The invention further includes a catalyst support tray having through holes that are sized and spaced to limit higher velocity regions within the catalyst bed and cause a more even distribution of the flow and thereby reduce hot spots within the catalyst bed.
