PROSPECTS OF THE USAGE OF SILICATE WASTE IN VANADIUM CATALYST TECHNOLOGY

The results of the use of silicate wastes (silica gel, sistof, microsilica) as alternative carriers in the technology of vanadium catalysts for the oxidation of sulfur dioxide were presented. The chemical and phase composition of silicate wastes, the parameters of the porous structure and the activity of the synthesized samples were studied. The prospects of microsilica use as carriers of catalysts for the oxidation of sulfur dioxide were shown basing on the analysis of physico-chemical and structural-strength characteristics of synthesized and industrial samples.
