A process for contacting a bed of particulate material, usually catalyst, with a transverse flow of fluid is disclosed. The particulate material moves or is prevented from not moving, while the fluid passes through the bed at a rate greater than the stagnant bed pinning flow rate. This invention is applicable to hydrocarbon conversion processes and allows for higher fluid throughput rates compared to prior art processes.

Method for passing a fluid through a moving bed of particles

An apparatus and process for stripping gases from solids comprises a structured packing in a stripping section of a vessel. The structured packing comprises a plurality of corrugated ribbons with each corrugated ribbon having at least two faces angular to each other. The ribbons at least partially obstruct passage of the solid particles. Edges of adjacent ribbons defining openings for the passage of contacted particles.
