Abstract

Gases containing sulphur dioxide and oxygen are fed to a gas generator charged with carbonaceous material and an alkali metal compound, the gas mixture obtained, while still hot, being mixed with a further regulated amount of sulphur dioxide and led to a chamber filled with catalyst to yield sulphur. The generator, which is preferably fitted with a revolving grate, may contain coke, coal or charcoal mixed or impregnated with sodium carbonate, sulphate or sulphide. Coke with 1 per cent by weight of sodium carbonate is suitable. The temperature is preferably 700--1100 DEG C., and can be regulated by varying the quantity of air supplied or by preheating the gas mixture. This mixture may be obtained by roasting pyrites or the like and preferably contains 4--5 per cent SO2 and 11 per cent O2 by volume. The gases leaving the generator are mixed with the further SO2, for example roaster gas containing 9--10 per cent SO2 and 4--5 per cent O2 and led to a chamber filled with brick, or bauxite or other materials containing iron, maintained at 500--800 DEG C., where the alkali metal compound forms an active coating. The sulphur produced is separated in coolers and Cottrell apparatus.
