Process for contacting a gaseous phase with at least one liquid phase and at least one divided solid phase

摘要

The invention relates to bringing a gas phase, at least one liquid phase and at least one solid phase in divided state into contact. The method consists in using a cell provided with at least one deflector such as an inclined wall 3, adapted to impose on the solid phase an overall movement of circulation and of a distributor 1 of the gas phase, to supply this cell with solid products. , to supply the latter in the liquid phase so as to completely cover the solid at rest, and to supply the cell in the gaseous phase through the distributor 1 to generate in said cell a periodic pulsating regime composed of expansion of the gaseous phase and of layer retractions. The invention makes it possible to ensure intimate contact between three distinct phases in order to obtain one or more transfers or one or more reactions between these phases.
