ABSTRACT:
A method and apparatus for exposing particles to a fluid including the steps of adding fluid and particles to a container having impeller means therein, generating a current with the impeller so as to subject the particles to centrifugal and convective forces resulting in the formation of a well-defined and localized fluidized bed of particles, and maintaining the existence of the current through the fluidized bed so that the particles are thereby exposed to the fluid. The fluidized bed is located in a region removed from the impeller when the particles are more dense than the fluid, and the fluidized bed is located in a region near the impeller when the particles are less dense than the fluid. A method of exposing a first fluid to a second fluid, the second fluid being either a gas or a liquid immiscible in the first fluid is also disclosed. The method includes the steps of adding the first and second fluids to a container having impeller means therein, generating with the impeller a current in the first fluid which subjects the second fluid to centrifugal and convective forces resulting in the formation of a well defined and localized bed of a dispersed phase of the second fluid remaining in a region near the impeller, and maintaining the existence of the current through the region so that the dispersed phase in the fluidized bed is exposed to the first fluid.
