Abstract

Patente de Invenção: <B>"MéTODO E COMPOSIçãO PARA A REGENERAçãO DE UM COMPOSTO AMìNICO"<D>. A presente invenção proporciona um método e uma composição para a regeneração de um composto amínico que tenha sido previamente reagido com um sulfeto selecionado a partir de sulfeto de hidrogênio e mercaptanos. O método inclui pór em contato uma mistura seq³estrante que inclui um composto amínico e um catalisador de oxidação com um gás, tal como o ar, ar enriquecido com oxigênio, oxigênio, ar enriquecido com ozónio e ozónio. A composição inclui um composto amínico, e um catalisador de oxidação. O método e a composição são úteis para a regeneração de um composto seq³estrante de enxofre com base em um composto amínico.
