甲氧化钒和含催化剂的SO 2氧化由预制承载体的浸渍浸渍含有钒和碱，在升高的温度和随后的激活浸渍过的载体体的热处理在750的温度下的解决方案，以SO 3的碱金属化合物 - 由氧化条件下1000℃ ， 为了制备浸渍溶液与除了VO还原剂和还原的酸性含水介质中细粒V2O5溶解<+>，其中酸和还原剂在大约化学计量的量被用于溶解，降低了V2O5。 所述碱被用作盐。 在该解决方案中，SO4-量设定为足以将碱成中性硫酸盐的全部量转换干燥和活化过程中。

A vanadium oxide and alkali metal compounds containing catalyst for the oxidation of SO₂ to SO₃ is contained by impregnation of prefabricated carrier bodies with impregnating solutions, the vanadium and alkalis, heat treatment of the impregnated carrier bodies at elevated temperature and subsequent activation at a temperature of 750 - 1000 ° C prepared under oxidizing conditions , To prepare the impregnating solutions fine-grained V₂O₅ is dissolved in an acid, aqueous medium with the addition of a reducing agent and reduction to VO²⁺, said acid and a reducing agent are used approximately in a stoichiometric amount to the dissolution and reduction of V₂O₅. The alkalis are used as salts. In solving a SO₄ amount is set, which is sufficient to convert the entire amount of the alkalis into neutral sulphates during drying and activation.
