METHOD AND APPARATUS FOR SEPARATING FINELY DIVIDED CATALYST PARTICLES FROM A GAS STREAM Abstract Catalyst particles suspended in a gas stream (especially the hot cracked oil vapors issuing from the riser of an FCC unit) are separated by subjecting the flowing suspension to a change of direction and permitting the catalyst particles to fall into a stripping zone. The hot gas stream is then rapidly transferred to a cyclone via a restricted passageway, minimizing the time that the gas is exposed to catalytic reaction temperatures.
