The catalytic removal of SO2 from combustion gases has been studied on the grain plane of a hard coal, being competitive with classical desulphurization processes. The method proposed for the removal of SO2 from combustion gases described in this paper is quite different from wet classical desulphurization methods. Studies of the influence of molybdenum concentration on the catalytic activity of a number of DESONOX catalysts are reported. The influence of the total surface area and other physicochemical properties of the catalyst on its behaviour have been studied.
