Abstract

resumo “método para a regeneração de um catalisador de desidrogenação usado” é fornecido um método para a regeneração de um catalisador de desidrogenação usado, utilizado na conversão de n-parafina em olefina. o método compreende as etapas para a remoção do coque por tratamento do catalisador com uma corrente de ozônio-oxigênio, seguido por uma corrente de oxigênio. o catalisador é estabilizado por passagem de uma corrente de nitrogênio e o catalisador estabilizado é rejuvenescido pela passagem de uma corrente de ar-nitrogênio contendo um hidrocarboneto halogenado. isto é seguido por redução do óxido de metal no catalisador, fazendo passar corrente de nitrogênio-hidrogênio.
