Abstract
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 (Da) is less than 1.
Claims19
A catalytic assembly comprising:
- a module comprising at least one layer of structural catalyst bodies, the layer having an inlet face for receiving a gas stream;
- and
- a diffuser assembly arranged a distance of greater than 50 mm from the inlet face, the diffuser assembly including a plurality of diffuser elements vertically integrated in the diffuser assembly, the diffuser elements comprising a plurality of apertures, the apertures of two or more diffuser elements being radially offset and/or laterally offset,
- wherein a ratio of aperture length (L) in the gas stream flow direction to aperture hydraulic diameter (Da) is less than 1.
A catalytic assembly comprising:
- a module comprising at least one layer of structural catalyst bodies, the layer having an inlet face for receiving a gas stream;
- and
- a diffuser assembly arranged a distance of greater than 50 mm from the inlet face, the diffuser assembly including a plurality of diffuser elements vertically integrated in the diffuser assembly, the diffuser elements comprising a plurality of apertures,
- wherein a ratio of aperture length (L) in the gas stream flow direction to aperture hydraulic diameter (Da) is less than 1 and aperture hydraulic diameter (Da) varies between the vertically integrated diffuser elements.
