Abstract
The method of preparation of modified Cu-substituted zeolite DeNOx catalyst s washcoated on monolith ceramics has been developed. Non-modified and modi fied monolith catalysts were tested in DeNOx reaction with propane. It was shown that the catalyst modified by cerium and containing titania together with H-ZSM-5 and Al2O3 in the washcoating layer demonstrates high level of activity, and its resistance during multiple cycles of poisoning by sulfur compounds and water at 400 and 500 degreesC is also high.
