摘要： The present invention relates to a multi staged cracking and stripping process that can be used in a fluidized-bed catalytic cracking process or FCC (fluidized catalytic cracking) process for maximizing the production of olefins, that is to say of C3 and C4 olefins, in particular propylene and distillates.One subject of the present invention is therefore a multi-staged process for cracking and stripping a fluidized mixture of hydrocarbons and of coked catalyst particles, integrated into a conventional fluidized-bed catalytic cracking process comprising at least one cracking step and one stripping step after separation of the particles of coked catalyst from the cracked effluent during the disengaging/stripping step, characterized in that it comprises at least two steps of cracking at least one hydrocarbonaceous fluid over the separated coked catalyst particles followed by at least two steps of stripping these particles, each cracking step preceding a stripping step. The present invention also relates to a separating and stripping device that implements this process.
