Abstract

"PROCESSO PARA A ELETRóLISE DE áCIDO CLORìDRICO DE GRAU TéCNICO CONTAMINADO COM SUBSTâNCIAS ORGâNICAS, USANDO CATODOS CONSUMIDORES DE OXIGêNIO". A presente invenção refere-se a um processo para eletrolisar uma solução aquosa de ácido clorídrico em cloro, em uma célula eletroquímica dotada com um compartimento catódico e um compartimento anódico, incluindo pelo menos um catodo de difusão de gás. O catodo de difusão de gás compreende um tecido eletricamente condutor, proporcionada em pelo menos um dos seus lados com um revestimento de um catalisador, que compreende sulfeto de ródio para a eletrorredução de oxigênio. O novo catalisador para uma redução de oxigênio tem uma estabilidade química aperfeiçoada para meios altamente corrosivos e uma alta atividade eletrocatalítica, na presença de contaminantes orgânicos.
