ABSTRACT:
A process for fluidizing a particulate solid and wherein the process uses an apparatus having a chamber with a fluid distributor at its base and containing at least one elementary compartment formed by a conduit having a cross-section "S", at least one obstacle at its base arranged symmetrically in relation to the axis of the conduit, each such compartment being fed with a quantity of the particulate product and with an upwardly flowing fluid, the particulate material being of at least 1 mm granulometry, the obstacle or obstacles of each cell being adapted to define an open inlet section "s" at its base for the fluid of a dimension given by 0.12.ltoreq.s/S.ltoreq.0.60; each cell is fed with a quantity of a particulate product so that the level of the product at rest in the cell is at most equal to a limit value approximately on the order of the height of the obstacle, and each cell is fed with fluid such that the flow velocity at the point of section S is at least equal to the minimum fluidization value of the particulate product and is lower than the pneumatic transport velocity of the large particles being carried by the fluid.
