    摘要： In order to achieve a high degree of conversion, oxides of nitrogen are contacted with a catalyst containing an aluminum silicate having a three-sheet structure as a catalytically active component at a temperature between 100.degree. C. and 700.degree. C. With this type of catalyst, the decomposition of the oxides of nitrogen proceeds without the presence of a reducing agent. Additionally, the degree of decomposition for the oxides of nitrogen is not adversely affected by the oxygen present in the flue gas. Degrees of decomposition greater than 60% were achieved with this catalyst in the temperature range between 200.degree. C. and 600.degree. C. The catalysts of the invention can replace the previous catalysts, which use a reducing agent, for decreasing the amount of oxides of nitrogen in waste gases, for example in flue gas and exhaust gas purification in power stations and combustion engines, respectively.

    摘要翻译： 为了实现高转化率，在100℃〜700℃的温度下，氮氧化物与含有三片结构的硅酸铝的催化剂接触，具有这种催化活性成分。 催化剂，氮的氧化物的分解进行而不存在还原剂。 此外，氮氧化物的分解程度不受烟气中存在的氧的不利影响。 该催化剂在200〜600℃的温度范围内，分解度达到60％以上。本发明的催化剂可代替先前使用还原剂的催化剂，以减少氧化物的量 废气中的氮气，例如分别在发电厂和燃烧发动机中的烟气和废气净化中。
