    Abstract: THE METHOD COMPRISES THE SQUENTIALY STEPS OF (1) PASSING AN INERT GAS THROUGH THE CATALYST BED AT A BED TEMPERATURE THAT IS BELOW THE INGNITION TEMPERATUTE OF COKE AND ANY ADDITIONAL NON-PUROPHORIC MATERIAL IN THE BED; AND (2) ADDING A CONTROLLED AMOUNT OF OSYGEN-CONTAINING GAS TO THE INERT GAS TO OXIDIZE THE PYROPHORIC MATERIAL. PREFERABLY, THE METHOD COMPRISES AN ADDITIONAL STEP OF MAINTAINING THE OXYGEN PARTIAL PRESSURE AT ABOUT 0.3 TO 1 ATMOSPHERE OF OXYGEN FOR A TIME THAT IS SUFFICIENT TO ELIMINATE ANY TEMPERATURE RISE THAT MAY OCCUR IN THE BED WHEN THE AMOUNT OF OXYGEN-CONTAINING GAS IS INCREASED.

    Abstract: The apparatus comprises: (1) a hollow first cylinder having an inlet end at its top and an outlet end at its bottom and having its axis in a vertical position; (2) a first baffle means located in said first cylinder near said inlet end and being positioned co-axially with said first cylinder, the diameter of said first baffle means being smaller than the inner diameter of said first cylinder; (3) a second baffle means located directly below said outlet end and being positioned co-axially with said first cylinder, the diameter of said second baffle means being at least as large as the inner diameter of said first cylinder; and (4) third baffle means being co-axial with said first cylinder and having its top connected to the bottom of said first baffle means and its bottom connected to the upper surface of said second baffle means and its vertical sides connected to the inner wall of said first cylinder. In a preferred embodiment, a support having a plurality of deflecting vanes extending downwardly therefrom and being positioned with one another along the periphery of a circle is connected to the cylinder near its outlet end and such vanes may be positioned at angles with the vertical and/or with the tangents of said circle. A plurality of gas jets may be used to disperse solid particles at said second baffle means and said second baffle means may comprise a conical section, a horizontal plate section, or both.

    Abstract: The apparatus comprises a plurality of baffles positioned in the vessel so as to be perpendicular to the flow of fluids through said vessel and a plurality of sets of swirl vanes that are assembled in such a manner that a fluid medium being introduced into the vessel between beds of solids will be intimately admixed with other fluids that are passing through the vessel from one bed of solids to another.
