Abstract: The invention concerns a collector assembly (8) for a gaseous fluid suitable for being disposed in a reaction section with a moving bed of catalyst of a radial reactor. The collector assembly comprises a vertical cylindrical screen (9), permeable to gas and impermeable to particles of catalyst, and a vertical cylindrical tube (10) which is supported by this screen (9) and disposed in a concentric manner with respect to the screen. The tube (10) comprises one or more zones (17a, 17b) which are permeable to gaseous fluid, comprising a plurality of through holes and a plurality of zones (18a, 18b, 18c, 18d) with a reduced permeability to gaseous fluid compared with the permeable zone. Each zone with a reduced permeability has a porosity, defined as the ratio between total permeable surface area of the zone and total developed surface area of this zone, in the range 0 to 0.005.

Abstract: The present invention describes a distributor plate provided with distribution elements having low sensitivity to a lack of horizontality, a distribution element being constituted by two substantially co-axial cylinders termed the inner cylinder (1) and the outer cylinder, the lower horizontal surface (5) separating the two cylinders being closed. The distributor plate is suitable for co-current downflows of gas and liquid, more particularly in “trickle bed” mode. The invention also concerns the application of the distributor plate to processes for the hydrotreatment or hydrogenation of various oil cuts.
