A cyclone and process for fluidized catalytic cracking of heavy oils is disclosed. Gas and entrained solids are added around a clean gas outlet tube in a cyclone body. Solids and some gas are withdrawn via a solids outlet and discharged into a catch chamber. Some of the gas discharged with the solids into the catch chamber is returned to the interior of the cyclone body via an opening in the cyclone. Chaotic reflux of gas back into the cyclone via the solids outlet is eliminated. The device may be used as an FCC regenerator third stage separator or to improve other gas/solid separations.
