1. the regenerating reactivating recovery system of a FCC equilibrium catalyst, it is characterized in that:

  • it comprises;

    pending discarded equilibrium catalyst enters in the multistage magnetic separating device (A) by material-transporting system;

    The low-magnetic agent that sorts out enters in the acidifying demetalization device (B);

    High-magnetic agent is drawn off pack;

    The slurries that acidified demetalization device (B) is handled enter in the activating apparatus (C), and add entry and activator in the slurries behind acidification reaction;

    Slurries behind the reaction certain hour are handled through filtering means dehydration device (D) and are formed filter cake;

    Enter drying unit (E) again;

    The finished product regenerated catalyst that filter cake obtains after the roasting in rotating and roasting device (F) flows out from converter continuously, gets final product after the packing of sieving;

    Whole process flow is controlled by automaton (G) and is shown.
