ABSTRACT:
An apparatus for regenerating coke-contaminated fluid catalyst is disclosed which comprises a vertical combustion chamber, an inlet to said chamber for spent catalyst and regeneration gas, a heat removal chamber located superadjacent to the combustion chamber and in communication therewith, heat removal means disposed within the heat removal chamber, a catalyst withdrawal conduit connected at one end to the heat removal chamber for withdrawing regenerated fluid catalyst from the heat removal chamber, and a catalyst recycle conduit connecting the withdrawal conduit with the lower portion of the combustion chamber, such that regenerated fluid catalyst can pass from the heat removal chamber to the combustion chamber. There may also be a means and control system for manipulating the extent of immersion of the heat removal means. A control system senses the catalyst temperature at an upper locus of the combustion chamber, formulates an output signal via a temperature control means having an adjustable set point, and regulates the flow rate of regenerated catalyst through the catalyst withdrawal conduit via transmission of said output signal to a flow control means responsive thereto.
