AMMONIA OXIDATION CATALYST |
摘要 |
Provided is a catalyst article for treating an emission gas comprising (a) a noble metal catalyst layer comprising one or more noble metals disposed on a first refractory metal oxide support; and (b) a vanadium catalyst layer comprising vanadium pre-fixed on a second refractory metal oxide support selected from alumina, titania, zirconia, ceria, silica, and mixtures of these, wherein the first catalyst layer is in physical contact with said second catalyst layer. Also provided is a method for making such a catalyst article, a method for treating gas emissions using such an article, and an emission gas treatment system incorporating such an article. |
