Abstract
Patente de Invenção: "PROCESSO PARA A REMOçãO DE COMPOSTOS DE ENXOFRE A PARTIR DE GASES". A invenção está direcionada a um processo para a redução catalítica de dióxido de enxofre a partir de uma mistura de gases, que contenha, pelo menos 10 % volume de água, em cujo processo a mistura de gases é passada sobre um catalisador de hidrogenação resistente ao enxofre, em forma sulfídica, em uma velocidade de espaço de pelo menos 2000 h^ -1^, na presença de um componente de redução que de preferência consiste pelo menos de forma parcial em hidrogênio, em uma proporção molar do componente de redução para o dióxido de enxofre de mais do que 10 e até 100, em uma temperatura de 125<198>C até 300<198>C, seguido pela passagem da mistura de gases, depois da referida redução, através de um leito seco de oxidação para a oxidação dos compostos de enxofre, de forma mais específica do sulfeto de hidrogênio, para o enxofre elementar.
