COBALT-CONTAINING BETA ZEOLITE, METHOD OF ITS PREPARATION, AND USE THEREOF IN CATALYZED REDUCTION OF NITROGEN OXIDES

摘要

The present invention relates to a catalyst for a selective catalytical reduction of nitrogen oxides, which contains beta zeolite having the content of aluminium in the lattice corresponding to Si/Al ratio in the range of from 3 to 8, and containing cobalt ions as active centers, and to its method of preparation. The invention also relates to a method of catalytic reduction of nitrogen oxides and use thereof.˙
