Abstract A special structure of FCC unit features that the catalyst and hydrocarbon are separated instantaneously, continuously and gravitationally in cracking operation with short contact time. The mixture of catalyst and hydrocarbon gas is filled in a separating container and central position by a transverse material-liquid contactor to vertically separate out catalyst from gas. The gas moves upward into an inertial separator, where the gas-carrying catalyst is separated out from hydrocarbon gas and collected at a higher position. The hydrocarbon absorbed by catalyst is stripped out from the catalyst.
