Abstract
Patente de Invenção: <B>"REMOçãO CATALìTICA DE ACETILENO NA DECOMPOSIçãO DE AR"<D>. A invenção abrange um processo para a remoção de acetileno na decomposição de ar em baixa temperatura. No caso, inicialmente o ar é comprimido, resfriado ao menos em um trocador de calor reversível e, a seguir, é decomposto ao menos em uma coluna de destilação. Consoante a invenção, antes do ingresso do ar no trocador de calor, o acetileno é cataliticamente oxidado a uma temperatura entre 70 a 130°C, de preferência entre 80 e 110°C. água e dióxido de carbono, por sua vez, são essencialmente removidos do ar no trocador de calor.
