Combustion of hard coal causes emission of gaseous chemicals (SO2, NOx), airborne particles and fly ashes into the atmosphere. The catalytic process of SO2 removal from combustion gases takes place on the grain plane of hard coal. The method proposed for the removal of SO2 from combustion gases is quite different from the classical wet desulphurization methods. This solution eliminates the technically complicated wet desulphurization of exhausts: sulphur within the hard coal reacts with catalyst compounds, which enriches the ashes with sulphates. Technical research has shown that the DESONOX type catalyst causes the lowering of both sulphur dioxide and nitrogen oxide emission from the exhaust coming from combusting the solid fuels. This document presents only the DESOX reactions using the DESONOX type catalysts. This paper reports on the studies concerning the methods of the DESONOX catalysts preparation and their influence on the amount of the generated sewage and on the catalytic activity of a number of DESONOX catalysts (during the course of the DESOX reaction). The results of the research on the influence of the catalysts physicochemical properties on their activity are also reported.
