Apparatus and process for increasing mixing in a fluidized bed. A slide, which may be in the form of a tube or trough, transports particles from an upper zone downward to a lower zone at a different horizontal position, thereby changing the horizontal position of the particle and creating lateral mixing in the fluidized bed. Increased mixing may improve efficiency for an apparatus using a fluidized bed. For example, increased lateral mixing in a regenerator may increase temperature and oxygen mixing and reduce stagnation to improve efficiency. A slide may be relatively unobtrusive, inexpensive, and simple for a retrofit or design modification and may improve combustion efficiency at high rates by enhancing the lateral blending of spent and regenerated catalyst.
