Catalytic reduction of sulfur dioxide on iron- alumina bifunctional catalysts

Article abstract of DOI:10.1021/i360038a003

Mixtures of alumina and iron powder provide efficient catalysts for the interaction of low concentrations of SO//2 with CO. The catalytic reaction rate at 500 C depended significantly on the iron content of the binary catalyst mixture. Mixtures containing 43% freshly reduced iron exhibited a sharp peak in the catalytic activity at 500 C when compared with other catalyst compositions. The normalized reaction rate per gram of iron, instead of per gram of total catalyst, still portrayed a sharp maximum when plotted against the weight fraction of iron in the catalyst.
