Abstract
Industrial gases containing sulphur compounds, particularly organic sulphur compounds, are purified by passing them over a lead oxide catalyst at a temperature between 180-250 DEG C. Lead monoxide is preferred and it may be employed in the form of a powder or granules, combined if desired with inert material. The process is particularly suitable for gases consisting largely of CO2 and in an example a gas containing 98.8 per cent CO2 and 5 mg/m3 of organic sulphur compounds is treated at 230 DEG C. and under a pressure of 160 atmospheres. The organic sulphur compounds were completely removed. In the purification of gases containing hydrogen and oxygen it is found that the oxygen content of the gases is reduced during the purification.
