Abstract

''CONJUNTO DE REFORMADOR DE VAPOR DE GáS COMBUSTìVEL HIDROCARBONETO, E, PROCESSO PARA FORMAR UM COMPONENTE RESISTENTE à DEPOSIçãO DE CARBONO'' Um conjunto de reformador de gás combustivel para uso em usina de energia de célula de combustível inclui passagens de gás combustível (2), que contém uma compactação de alumina em partículas (12) em que uma mistura de corrente de vapor - combustível hidrocarboneto vaporizada é aquecida. As paredes (4) das passagens (2) tem um revestimento de alumina que protege as paredes (4) da corrosão. O revestimento (4) e compactação (12) são sobrepostos por uma camada de óxido de metal alcalino-terroso que limita o acúmulo de carbono sobre as superfícies das paredes (4) e evita o entupimento prematuro das passagens (2). A camada limitadora do acúmulo de carbono é formada em componentes das passagens do reformador por aplicação de uma suspensão à base d'água de compostos de metal alcalino-terroso para as superfícies da passagem do reformador, e então secagem da suspensão para solidificar a mesma. O material de compactação revestido (14) é operativo para converter qualquer carbono livre restante na corrente de gás para dióxido de carbono, ou monóxido de cabono, assim ainda limitando a deposição de carbono no conjunto.
