โœฆ Synopsis

Abstract

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 7โ€“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.

## Abstract The dissolution of sulphur in copper oxides leads to modifications of the ionic and electronic defect structures, causing anion and cation mobilities and possibly the electron hole concentration to be increased. No clear explanation or mechanism for these effects is available so far. Th
