ABSTRACT:
A catalyst regeneration apparatus for the oxidation of coke from a spent catalyst and for the conversion of carbon monoxide resulting from the oxidation of coke to carbon monoxide.
The apparatus comprises in combination and particular arrangement a spent-catalyst receiving chamber for containing a dense-bed of fluidized catalyst in which chamber spent catalyst is oxidized to produce regenerated catalyst and partially-spent regeneration gas; a transfer conduit through which partially-spent regeneration gas and regenerated catalyst pass and in which carbon monoxide is essentially completely converted to carbon dioxide to produce spent regeneration gas and regenerated catalyst at an increased temperature; a regenerated-catalyst receiving chamber for containing dense-bed of regenerated catalyst and in which spent regeneration gas and regenerated catalyst are separated; and, an internal regenerated-catalyst recycle means by which hot regenerated catalyst can be recycled from the transfer conduit to the spent-catalyst receiving chamber in amounts to increase the temperature and hence the rate of coke oxidation in the spent-catalyst receiving chamber.
