The rate of catalytic oxidation of sulphur dioxide on the surface of mild steel, aluminium sprayed and aluminized steel is reported. The effect of variation in temperature, gas velocity and concentration of sulphur dioxide has been measured. The presence of water vapour has been shown to inhibit catalytic oxidation on the surfaces tested. The catalytic activity of mild steel increases considerably upon exposure; aluminium sprayed specimens exhibit a maximum in catalytic activity after 7–12 hours' exposure with a decrease upon further exposure; aluminized specimens show constant catalytic activity. Coating steel with aluminium considerably reduces the rate of catalytic oxidation of sulphur dioxide.
