This paper reports the study of the relation between sulphur dioxide adsorption and sulphur dioxide removal degree from exhaust gases on DESONOX type catalysts based on the synthetic zeolite Sipernat impregnated with vanadium ions by the double impregnation method, with the use of the EDTA solution (first impregnation step) and NaOH with V2O5 solution (second impregnation step) for different periods of time: 4, 16 and 32 minutes. The studied materials are designated as: support – Sipernat, catalysts: Sipernat VX, where X is the impregnation time in minutes. The sulphur dioxide adsorption for all catalysts was smaller than that for the Sipernat support. The active material (vanadium ions) decreased the amount of sulphur dioxide adsorption centers. The samples, which adsorb smaller amount of sulphur dioxide, are better DESONOX catalysts. The sample Sipernat V16 is the best of the studied catalysts.
