Abstract The present invention discloses a kind of striping method and equipment to eliminate entrained foreign gas of catalytic conversion regenerated catalyst. The regenerated catalyst is stripped first in a stripper inside the regenerator and then in an other stripper outside the regenerator. By using the two-stage stripping method and equipment of the present invention, the regenerated catalyst can have its 80-90% entrained foreign gas eliminated, and this can reduce greatly the foreign gas entrained brought into the reactor by the regenerated gas and the foreign gas in oil-gas inside the reactor and simplify the subsequent separation and refining of reactant.
