Abstract

UN CATALIZADOR DE PIROLISIS DE HIDROCARBURO CON DEPOSITOS DE COQUE, SE REGENERA MEDIANTE LA COMBUSTION DE LOS DEPOSITOS EN UN REGENERADOR (2) CON UNA ZONA DE COMBUSTION INFERIOR (12) Y UNA ZONA REDUCTORA SUPERIOR (14). UNA MEZCLA DE OXIGENO Y UN GAS INERTE (POR EJEMPLO NITROGENO O DIOXIDO DE CARBONO) SE INTRODUCE EN LA ZONA DE COMBUSTION (12) A TRAVES DE UN DISTRIBUIDOR. LA ZONA DE COMBUSTION (12) TIENE AL MENOS UN 24% DE VOLUMEN DEL INDICE DE FLUJO TOTAL DE TODOS LOS GASES EN LA ZONA (12). SE COMBUSTIONA AL MENOS PARTE DEL COQUE. ADEMAS, EL NITROGENO EN EL COQUE SE CONVIERTE A OXIDOS DE NITROGENO (NO{SUB,X}). UN GAS DE COMBUSTION SUSTANCIALMENTE SIN OXIGENO, INCLUYE UN DIOXIDO DE CARBONO, OXIDOS DE NITROGENO Y AL MENOS UN 1% DE VOLUMEN DE MONOXIDO DE CARBONO, QUE FLUYE EN LA ZONA REDUCTORA (14) CON EL RESULTADO DE AL MENOS PARTE DE LOS OXIDOS DE NITROGENO REDUCIDOS A NITROGENO.
