Abstract
In many laboratory hot corrosion HC experiments and other experiments involving sulfur commercial catalytic converters are used to catalyze the textSO 2 + 1/ 2 textO 2 to textSO 3 reaction The conversion rate of SO2 to SO3 highly depends on the catalyst used and thus the HC results especially in lowtemperature HC conditions may vary significantly depending on the catalyst selected Different elements present in the catalyst affect the SO2 to SO3 conversion and with it the degree of HC induced attack Modern automotive catalysts have low activity for the oxidation of SO2 to SO3 The conversion of SO2 to SO3 can be enhanced by modifications of the catalyst eg by using a Ptgauze or dipcoating the catalyst in a Fe2O3 solution
