Abstract

PROCEDIMIENTO Y APARATO DE REGENERACION DE CATALIZADORES DE RECONVERSION QUIMICA. EL PROCEDIMIENTO CONSISTE EN SOMETER AL CATALIZADOR A UN CALENTAMIENTO PROGRESIVO HASTA UNA TEMPERATURA COMPRENDIDA ENTRE 700 Y 850GC, EN PRESENCIA DE UNA ATMOSFERA OXIDANTE QUE CIRCULA EN EL MISMO SENTIDO QUE EL CATALIZADOR. EL TIEMPO DE TRATAMIENTO ESTA COMPRENDIDO ENTRE TREINTA MINUTOS Y DOS HORAS, LA TEMPERATURA ESTA COMPRENDIDA ENTRE 650 Y 700GC. EL PROCEDIMIENTO DE REGENERACION SE EMPLEA DE MODO CONTINUO. EL APARATO CONSTA DE UN HORNO GIRATORIO QUE LLEVA SOBRE LA PARED INTERIOR DE SU PARTE BAJA ALETAS RADIALES Y EN SU EXTREMIDAD INFERIOR, EN LA SALIDA, UN DIAFRAGMA. EN LA PARTE INFERIOR DEL HORNO VA ACOPLADA UNA CHIMENEA QUE RECOGE EL CATALIZADOR REGENERADO Y LA PARTE ALTA CANALIZA LOS HUMOS DE TOSTACION.
