Filed:

Dec 16, 1974

Appl. No.:

5/533052

Inventors:

Richard P. Pulak - Palatine IL

Assignee:

Universal Oil Products Company - Des Plaines IL

International Classification:

B01J 808
B01J 818
B01J 3714

US Classification:

23288B

Abstract:

An apparatus for the oxidation of coke from an FCC spent catalyst is disclosed which 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 said gas and said 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; an internal regenerated catalyst recycle means by which a portion of hot regenerated catalyst can be recycled from the transfer conduit to the spent-catalyst receiving chamber; a regenerated-catalyst receiving chamber for containing a dense-bed of regenerated catalyst and in which spent regeneration gas and regenerated catalyst are separated; and, an external regenerated-catalyst recycle means by which a portion of hot regenerated catalyst can be recycled from the regenerated-catalyst receiving chamber to the spent-catalyst receiving chamber.

5/676254

Richard P. Pulak - Palatine IL

US Classification:

23288B

Abstract:

A catalyst regeneration process and apparatus for the oxidation of coke from a spent catalyst and for the conversion of CO resulting from the oxidation of coke to CO. sub. 2. Novel feature of the process is the mixing of a portion of regenerated catalyst produced in a coke oxidation zone and heated to a higher temperature in a CO-conversion zone with spent catalyst and passing the mixture to a coke-oxidation zone to increase the temperature within the coke oxidation zone and to disperse spent catalyst more evenly across that zone thereby increasing the rate, extent and evenness of coke oxidation. The regeneration apparatus includes components by which this can be accomplished.

International Classification:

US Classification:

23288B

Abstract:

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 said gas and said 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 a dense-bed of regenerated catalyst and in which spent regeneration gas and regenerated catalyst are separated; and, a regenerated-catalyst recycle means by which hot regenerated catalyst can be recycled within the apparatus from the regenerated-catalyst receiving chamber to the spent-catalyst receiving chamber in amounts to control the temperature and hence the rate of coke oxidation in the spent-catalyst receiving chamber. Residual coke on regenerated 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 regeneration gas leaving the apparatus is therefore reduced.

Abstract:

An apparatus for the oxidation of coke from a spent catalyst at a controlled temperature and for the essentially complete conversion of carbon monoxide resulting from the oxidation of coke to produce regenerated catalyst and spent regeneration gas. 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 said gas and said 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, a regenerated-catalyst recycle means by which hot regenerated catalyst can be recycled from the transfer conduit or the regenerated-catalyst receiving chamber to the spent-catalyst receiving chamber in amounts to control the temperature and hence the rate of coke oxidation in the spent-catalyst receiving chamber.
