Influence of the Vanadium and Zinc Contents in DESONOX Catalysts on the Course of the DESOX Reaction

Abstract

The catalytic process of SO 2 removal from combustion gases takes place on the grain plane of hard coal. This process is competitive relative to classical desulphurization processes. The method proposed for the removal of SO 2 from combustion gases described in this paper is quite different from wet classical desulphurization methods. This paper reports studies of the influence of vanadium and zinc concentration on the catalytic activity of a number of DESONOX catalysts (in the course of the DESOX reaction). Investigations of the influence of the total surface area and other physicochemical properties of the catalyst on its behaviour are also reported.
