Abstract
"PROCESSO PARA A CONVERSãO CATALìTICA DE GASES COM ALTO CONTEúDO DE DIóXIDO DE ENXOFRE". Uma mistura de gases com oxigênio molecular e 15 a 60% em volume de SO~ 2~ corre através de uma primeira camada de catalisador, que contém um catalisador contendo pentóxido de vanádio, e, de modo imediatamente subseq³ente, através de uma segunda camada de catalisador, que contém um catalisador contendo ferro. A mistura de gases é guiada com uma temperatura de entrada de 350 a 600<198>C para a primeira camada de catalisador, que contém um catalisador de V2O5 granulado e 20 a 80% em peso de material inerte cataliticamente inativo. De modo imediatamente subseq³ente, a mistura de gases é guiada com uma temperatura de 500 a 750<198>C para a segunda camada de catalisador. Preferivelmente, o catalisador da segunda camada de catalisador contém 3 -30% em peso de óxido de arsênico. é produzido um gás de produto que contém SO~ 3~, com uma relação de volume de SO~ 2~: SO~ 3~ de, no máximo, 0,1.
