ABSTRACT:
The present invention is concerned with the method of regenerating the fluidizable, catalytic, particulate solids in the regenerator section of an FCC process, and RCC process or a metals removal system or "ART" type process. It is directed to the use of a conduit means for charging fluidizing gaseous material to a vertical cylindrical vessel for cooling fluidizable particulate solids flowing through said vertical cylindrical vessel, which conduit means comprises a horizontal header means having suspended therefrom a plurality of vertical and horizontally spaced apart conduits, each conduit having near its open end a restriction orifice. The header means is located near the top of the cylindrical cooling vessel. One portion of the vertical conduits has lower ends located in the upper half of the vessel and a second portion of the vertical conduits has lower ends located in a lower half of the vessel.
