Briefly, in one aspect, a catalytic assembly described herein comprises a module comprising at least one layer of structural catalyst bodies having an inlet face for receiving a gas stream. A diffuser assembly is arranged a distance of greater than 50 mm from the inlet face, the diffuser assembly including at least one diffuser element comprising a plurality of apertures, wherein a ratio of aperture length (L) in the gas stream flow direction to aperture hydraulic diameter (D) is less than 1.

Diffuser assemblies and catalytic reactors comprising the same

The present invention relates generally to catalysts and, in particular, relates to in-situ replacement of catalyst within a reactor. In an embodiment, the present invention comprises a method for the in-situ replacement of catalyst bodies in a catalytic reactor comprising removing catalyst bodies in-situ from at least one modularized section of a catalytic layer within a catalytic reactor and replacing the removed catalyst bodies in-situ with replacement bodies comprising catalytic function wherein at least 10% of the total catalyst bodies within the layer are replaced.
