Abstract

PROCEDIMIENTO PARA LA REGENERACION DE UN CATALIZADOR DEL TIPO DE FOSFATO DE HIERRO, QUE SE USA TIPICAMENTE PARA LA OXIDESHIDROGENACION DE HIDROCARBUROS. COMPRENDE UNA ETAPA EN LA QUE EL CATALIZADOR SE SOMETE A UNA ATMOSFERA OXIDANTE, PREFERIBLEMENTE INTERRUMPIENDO EL FLUJO DE ALIMENTACION ORGANICA A TRAVES DEL LECHO CATALITICO, SEGUIDO DE UNA ETAPA EN LA QUE EL CATALIZADOR SE SOMETE A UNA ATMOSFERA REDUCTORA, PREFERIBLEMENTE INYECTANDO LA ALIMENTACION ORGANICA SOBRE EL CATALIZADOR EN AUSENCIA DE OXIGENO. EL METODO SE DESCRIBE, ESPECIFICAMENTE, CON RESPECTO A LA PRODUCCION DE ACIDO METACRILICO POR OXIDESHIDROGENACION DE ACIDO ISOBUTIRICO.
