Abstract

PROCEDIMIENTO PARA LA REGENERACION DE UN CATALIZADOR MULTIMETALICO QUE CONTIENE PLATINO SOBRE SOPORTE Y QUE SE HA DESACTIVADO, AL MENOS PARCIALMENTE, DEBIDO A LOS RESIDUOS CARBONOSOS DEPOSITADOS SOBRE ELLOS EN LA CONVERSION DE HIDROCARBUROS. SE REGENERAN MEDIANTE: 1) CONTACTO DEL CATALIZADOR CON OXIGENO PARA QUEMAR LOS RESIDUOS CARBONOSOS; 2) CONTACTO POSTERIOR CON HIDROGENO A TEMPERATURA ELEVADA, PARA CONVERTIR UNA PORCION SUSTANCIAL DEL COMPONENTE NO PLATINICO PRESENTE EN EL CATALIZADOR, EN SU FORMA METALICA; 3) CONTACTO DEL CATALIZADOR REDUCIDO CON HALOGENURO DE HIDROGENO SECO, EN AUSENCIA DE OXIGENO; 4) TRATAMIENTO CON CLORO DEL CATALIZADOR TRATADO CON HALOGENURO DE HIDROGENO; Y 5) REDUCCION DEL CATALIZADOR TRATADO CON CLORO, CON UN AGENTE REDUCTOR, TAL COMO HIDROGENO.
