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

In one aspect, catalyst modules are described herein comprises structural catalyst bodies having cross-sectional flow channel geometries and surface features for enhanced catalytic activity. In some embodiments, the catalyst modules and associated structural catalyst bodies are suitable for use in high particulate matter environments. Briefly, a catalyst module comprises a framework and a plurality of structural catalyst bodies positioned in the framework, a structural catalyst body comprising an outer peripheral wall and a plurality of inner partition walls forming individual flow channels of rectangular cross-section, the outer peripheral wall resistant to localized flexural failures induced by material between adjacent structural catalyst bodies of the module.
