ABSTRACT:
A fluidized bed process is disclosed which comprises subjecting a bed comprised of solid particulate magnetizable, fluidizable material within an external force field wherein at least a portion of the bed containing said solid particulate magnetizable and fluidizable material and fluidizing fluid are subjected to a nontime varying and substantially uniform applied magnetic field having a substantial component along the direction of the external force field such that said solid particulate magnetizable and fluidizable material has a component of magnetization along the direction of the external force field and wherein at least a portion of said bed containing the solid particulate magnetizable and fluidizable material is fluidized by a flow of fluid opposing said external force field at a superficial fluid velocity ranging between:
