| Abstract: | Analyzes the unstable fluidization in semi-regeneration chute of eclipsed form two-stage regeneration unit.Through increasing catalyst density、gas removing from semi-regenerator chute inlet and adjusting air flow rates at loose points in 1st regenerator bed,revamping the main air distributing tube、adjusting catalyst fine powder content and process operation in the 2nd regenerator,the problem of unstable fluidization in semi-regeneration chute is solved. |
