Abstract
Hydrogen sulphide is obtained by the action of steam at high pressure, say 35 or 45 atmospheres, and raised temperature on sulphur or substances which contain or yield up sulphur, for example iron pyrites or spent gas purification material. The steam may be produced in the reaction chamber by the addition of water thereto.
