This paper reports studies on the influence of vanadium concentration on the catalytic activity of DESONOX catalysts (in DESOX reaction) based on modified montmorillonite from Jelsovy Potok. The investigation of the influence on the physicochemical properties of the catalysts on their behaviour has also been studied.

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.

The catalytic process of the removal of SO2 from combustion gases takes place on the grain plane of hard coal. This process is competitive with regard to 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. This paper reports the studies on the influence of vanadium and zinc concentration on the catalytic activity of number DESONOX catalysts (in the course of DESOX reaction). It also investigates the influence of the vanadium concentrate in the catalyst, total surface area and other physico-chemical properties of the catalyst on the behaviour.

W pracy przedstawiono wpływ stężenia wanadu, oraz innych właściwości fizykochemicznych katalizatorów DESONOX, na ich aktywność w reakcji usuwania SO2 z gazów spalinowych pochodzących ze spalin węgli kamiennych. Stwierdzono wyraźny wpływ zawartości V w badanych katalizatorach na ich aktywność oraz wpływ dodatku dolomitu, jako substancji alkalizującej odpady paleniskowe. Zauważono, że dodatek dolomitu nie zmienia mechanizmu reakcji DESONOX, lecz jedynie podnosi aktywność właściwą badanych katalizatorów DESONOX.
