The present invention relates to a device and respective process for distribution of mixed charges comprising a flat tray in the form of a disc drained by a series of drainage tubes located above the surface of fixed beds of catalysts, capable of promoting the homogenisation and distribution of charges by means of said device. Such drainage tubes mounted in said manner have the objective of restricting and reorienting the flow of mixed charges, multiplying the points whereon they fall, principally of the liquid phase, onto said beds of catalysts. For the purpose of doing so said drainage ducts, being segments of tubes, distributed on the entire surface of said tray possess caps affixed at the upper extremity thereof impeding the direct flow of charge onto the bed of catalyst, creating a reservoir of liquid on the tray, subsequently being drained down such device in a more controlled manner.

Device and process for distribution of mixed charges onto fixed beds of catalyst in descending-flow reactors

A distributor nozzle for a two-phase charge, to be used in fixed-bed reactors in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the whole area of the bed in the reactor. The device includes a number of fixing bars and a deflector cone frustum. The deflector cones or cone frusta may have more than one angle in order to improve the distribution, and they have a number of apertures or slits and a number of vertical directing elements or a directing cage or frame to direct the stream of the two-phase charge in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the entire area of the bed in the reactor.
