DEVICE FOR MIXING AND DISTRIBUTING A DENSE FLUID AND A LIGHT FLUID, PLACED UPSTREAM FROM A GRANULAR BED, AND ITS USE IN DESCENDING FLOW

摘要

High-density fluid (usually liquid), and low-density fluid apparatus (generally gas) mixing and dispensing being disposed between the two particle layer that is or continuously in the particle layer 70, the reaction chamber of the upstream, the device is outside of the reactor a dense fluid characterized in that from the pipe system 50 is positioned adjacent to the upper horizontal plate, preferably approximately level horizontal plate (62) for the introduction to a level lower than the interface between the achieved level of the dense fluid and the low density fluid. This device, used in particular to any type of gas / liquid reaction in a fixed bed for the hydrogenation.
