PROBLEM TO BE SOLVED: To provide an improved device for mixing and distributing a gas and a liquid phase on a granular bed.;SOLUTION: In this device for mixing and distributing the liquid phase and the gas phase inside a vertical reactor on the upstream of the granular bed or between two successive granular beds, the device comprises: a substantially horizontal plate 20 covering the entire cross section of the reactor and supporting a plurality of substantially vertical conduits 40 comprising an upper end 43 communicating with a portion of the reactor located above the plate and a lower end 21 communicating with a portion of the reactor located below the plate; the conduits comprise lateral orifices 42 at different levels disposed along their vertical walls and allowing the gas phase and the liquid phase to be introduced into the conduits at least partially in a separated manner; the device comprises a substantially vertical inner wall 30 located in a space between the outer wall 13 of the reactor and a zone occupied by the conduits, and defining, together with the outer wall, an annular zone 28 for receiving at least the liquid phase from outside the reactor and which communicates with the central portion of the plate, in particular by means of lower sections 32 for flow.;COPYRIGHT: (C)2005,JPO&NCIPI
