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.
