Estimating the term…
This invention relates to a plate that allows the distribution of a polyphase mixture in a reactor that operates in the trickle mode and that consists of at least one gaseous phase and at least one liquid phase, with the plate (10) being located above a catalytic particle bed, comprising a number of shafts (3), characterized in that a portion of the shafts of the plate, located close to the wall of the reactor chamber, called peripheral shafts, are truncated. The invention also relates to the use of the plate in a reactor for the purpose of carrying out reactions of hydrotreatment, hydrogenation, or oxidation.
Distributor plate (10) that makes it possible to ensure the distribution of a polyphase mixture in a reactor, the plate (10) being located in the upper part of the reactor above a catalytic particle bed (30) and consisting of a number of shafts (3) that are equipped with openings (4) that are distributed over a portion of their height, characterized in that the portion of the shafts located on the periphery of the plate (so-called peripheral shafts) has a height Hp that is strictly lower than the height Hc of the shafts located at the center (so-called central shafts), whereby these peripheral shafts do not have an opening at their upper end, the central shafts in contrast having an opening (5) at their upper end, with the peripheral shafts being located at a distance D1 from the wall (1) of the reactor of between 25 and 450 mm.
