Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA REDUCCION CATALITICA DE NO CONTENIDO EN UN GAS CONSISTENTE DE SO2 CON NH3, EN EL QUE EL GAS CONTENIENDO SO2 Y NO SE MEZCLA CON NH3, LA MEZCLA EN EL CATALIZADOR SE LLEVA UNA CANTIDAD DE 0,2 A 20 NI/MIN Y POR G CATALIZADOR Y ALLI SE LLEVA EN 185 A 500 C ASI COMO A PRESION NORMAL EN EL AGITADOR A REACCION, CON LO QUE EL CATALIZADOR TIENE UN TAMAÑO DE PARTICULA DE 0,1 A 3MM Y SE COMPONE DE UN SOPORTE ACIDO ASI COMO UN COMPONENTE ACTIVO Y CON LO QUE EL COMPONENTE ACTIVO CONSTA DE V2O5, MNO5, CUO, FE2-O3, NIO Y/O Y2O3 ASI COMO SE LLEVA EN UNA CANTIDAD DE 0,5 A 20% DE PESO EN EL CATALIZADOR. SE PROPONE EL AGITADOR TOME UNA PARTE DEL CATALIZADOR PARA REGENERAR Y SEGUIDAMENTE LA VUELVA A LLEVAR EN EL AGITADOR CON LO QUE LA REGENERACION PUEDE CONSEGUIRSE TANTO POR LA VIA HUMEDA COMO POR LA SECA.
