Yields of SO 2 formed during H 2 S removal from N 2 + H 2 S mixture at 800°C in the presence of Fe 2 O 3 , Mn-nodule and red mud have been determined. The largest yields were observed for Fe 2 O 3 followed by Mn-nodule, whereas no SO 2 was detected in the presence of red mud. A mechanism for H 2 S reaction with Fe oxides has been proposed involving the use of the component distribution in the clean gas as well as the Fe sulphides formed during adsorption. X-ray diffraction and Mossbauer spectroscopy have been used to determine the forms of Fe in the solids at the end of adsorption. FeS was the main sulphide which was always accompanied by FeS 2 .
