Abstract

SE REDUCEN LAS EMISIONES DE OXIDOS DE NITROGENO (NOX) DE UN REGENERADOR DE FCC FORZANDO AL GENERADOR A FUNCIONAR EN MODO PARCIAL DE QUEMA DE CO Y MEDIO A MEDIAS. FUNCIONANDO CON MENOS DE 1% MOLAR DEO2 Y HASTA 1 O 2 PORCIENTO DE CO EN EL GAS DE COMBUSTION CREA CONDICIONES QUE OXIDAN LOS COMPUESTOS DE NITROGENO EN COKE EN CATALIZADOR PASADO A NOX Y CONVIERTEN SIMULTANEAMENTE NOX EN EL REGENERADOR EN NITROGENO. UNA CALDERA DE CO CORRIENTE ABAJO PUEDE QUEMAR SU GAS DE COMBUSTION BAJ EN CO SIN PRODUCIR GRANDES CANTIDADES DE NOX. LA MAYOR PARTE DE LAS EMISIONES DE NOX PUEDE ELIMINARSE. TAMBIEN SE PRESENTA UN APARATO, CON LA RELACION AIRE/COKE DE REGENERADOR CONTROLADA POR AMBOS ANALIZADORES DE CO Y O2 QUE CONTROLAN EL GAS DE COMBUSTION DE REGENERADOR.
