Abstract

MéTODOS PARA PROLONGAR A UTILIZAçãO DE UM CATALISADOR". A presente invenção fornece um método para prolongar a utilização de um catalisador em um sistema de reação multifásico, sendo que uma reação primária e uma reação de envenenamento do catalisador secundária (ou mais) ocorrem no mesmo catalisador, e a velocidade de reação de envenenamento de catalisador secundária (ou mais) é maior que a velocidade de reação primária.
