摘要： Catalysts, catalyst systems, and methods for removing ammonia and/or carbon monoxide in flue gases are provided where ammonia is used with a selective catalytic reduction catalyst for reducing oxides of nitrogen. A dual oxidation catalyst generally comprises an alkali component, a transition metal, and a metal oxide support. This catalyst is also substantially free from precious metal components and effective for substantially simultaneously oxidizing ammonia (NH3) and carbon monoxide (CO) when placed in an exhaust gas stream. The catalyst is effective to provide low ammonia to nitrogen oxides selectivity.

摘要： Methods are disclosed for providing a library of composite compositions on a support. The method involves depositing one or more components onto the support on either discrete spaced regions of the support or as a continuous concentration gradients on the surface of the support. The composite samples can be removed from the support by drilling out portions of the coated support so as to yield individual composite tablets containing the support with one or more component layers thereon. By using this method, a vast number of composites can be made and tested simultaneously.
