Spent catalyst regeneration apparatus with internal and external regenerated-catalyst recycle means |
摘要 |
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.
