Scr catalyst for nitrogen oxide reduction in the case of high temperatures

摘要

It is a method for producing a copper - zeolite - catalyst for the selective catalytic reduction of nitrogen oxides is provided, wherein the method of an acid treatment of a zeolite matrix, a calcining the zeolite matrix, and a subsequent introduction of copper - and optionally further metal ions, and wherein between these steps in the case of a calcination is carried out by means of 700°C. The method can be achieved with a pure zeolite matrix or an already copper-containing zeolite matrix be carried out. It is furthermore a catalyst produced is provided with the method.
