ABSTRACT OF THE DISCLOSURE An apparatus for the controlled oxidation of coke from a spent catalyst and the essentially complete conversion of carbon monoxide resulting from the oxidation of coke to pro- duce regenerated catalyst and spent regeneration gas. The apparatus comprises in combination a spent-catalyst receiving chamber for containing a dense bed of fluidized catalyst in which chamber spent catalyst is oxidixed to produce regenerated catalyst and partially spent regeneration gas; a transfer conduit through which said gas and said catalyst pass and in which carbon monoxide is essentially completely convert- ed to carbon dioxide to produce spent regeneration gas and regenerated catalyst at an increased temperature; a regenerated- catalyst receiving chamber for containing a dense bed of reg- enerated catalyst and in which spent regeneration gas and re- generated catalyst are separated; and, an internal regenerated- catalyst recycle means in communication with both beds by which hot regenerated catalyst can be recycled within the apparatus from the dense bed of regenerated catalyst in the regenerated- catalyst receiving chamber to the dense bed of catalyst in the spent-catalyst receiving chamber in amounts to control the temper- ature and hence the rate of coke oxidation in the spent-catal- yst receiving chamber. In the apparatus of my invention, residual coke on re- generated catalyst can therefore be significantly reduced or controlled to low levels as desired. The CO burning rate in the transfer conduit is also increased because of the higher inlet temperature and the CO concentration in the spent regener- ation gas leaving the apparatus is therefore reduced. A particularly unique feature of the apparatus is the internal regenerated-catalyst recycle means which requires no expansion joints nor movable flow control means and which can be installed without cutting into either chamber of the apparatus. -2-
