ZONED AMMONIA SLIP CATALYST FOR USE IN COMBUSTION TURBINES |
| 摘要 |
A catalytic article for treating an exhaust gas stream containing one or more of NOx, hydrocarbons, CO, SOx and ammonia from a combustion turbine comprises (a) a substrate having an inlet end and an outlet end defining an axial length; (b) an oxidation layer comprising an oxidation catalyst comprising one or more noble metals, the oxidation layer being positioned on the substrate and covering the axial length of the substrate; and (c) an SCR layer comprising an SCR catalyst, the SCR layer being positioned on the oxidation layer and overlapping a portion of the oxidation layer, wherein the portion is less than 100%. |

1. A catalytic article for treating an exhaust gas stream from a combustion turbine, comprising:
(a) a substrate having an inlet end and an outlet end defining an axial length; (b) an oxidation layer comprising an oxidation catalyst comprising one or more noble metals, the oxidation layer being positioned on the substrate and covering the axial length of the substrate; and (c) an SCR layer comprising an SCR catalyst, the SCR layer being positioned on the oxidation layer and overlapping a portion of the oxidation layer, where the portion is less than 100%, where the article is configured for treating an exhaust gas stream containing one or more of NOx, hydrocarbons, CO, SOx and ammonia from a combustion turbine. |
