This invention relates to a device for cooling and distributing mixed charges on fixed catalyst beds for use in the cooling zone of descending flow reactors which comprises a flat tray fitted with collector and distributor tubes for liquid superimposed upon and connected to another flat tray of similar design to the upper tray. The device, which is of smaller size in comparison with other commercially available devices, is extremely simple to install industrially and compact, and has as its main characteristic the efficiency with which it promotes reduction of the temperature of the reaction medium when it receives the cooling fluid within the catalytic reactor.

Device for cooling and distributing mixed charges on fixed catalyst beds

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.
