ABSTRACT:
The invention relates to contact-making between a gas phase, at least one liquid phase, and at least one comminuted solid phase.
The process uses a cell or compartment provided with at least one deflecting means such as the sloping wall 3 designed to impart an overall circulatory motion to the solid phase and with gas phase distributor 1, supplying this compartment with solid products, supplying this compartment with a liquid phase so as to cover entirely the solid when at rest, and feeding the compartment with the gas phase through the distributor 1 for the purpose of generating in said compartment a periodic pulsing stage consisting of gas-phase decompressions and layer contractions.
The invention permits achieving an intimate contact between three distinct phases for the purpose of transfer(s) or of reaction(s) between these phases.
