Abstract
Reduction of sulphur dioxide, esp. that contd. in water gases, is effected by contacting the gas with granular coal in the presence of steam, so that the coal is oxidised and the sulphur dioxide is reduced to sulphur and/or hydrogen sulphide. A cheap agent e.g. coal with a high sulphur content, can be used. Reduction is effected at a relatively low temp.
