一种脱除烟气中NO的催化剂及其制备方法
摘要：
本发明公开了一种脱除烟气中NO的催化剂及其制备方法，以解决现有的采用FCC废催化剂脱除烟气中NO的方法所存在的NO的脱除率较低、烟气中SO2的存在会大大降低NO的转化率、使用NH3为还原剂存在缺点等方面的问题。本发明催化剂包括70w％～85w％的Al2O3、5w％～15w％的CeO2、3w％～15w％的CuO、50～350μg/g的Pd，本发明公开了其制备方法。本发明催化剂主要应用于采用FCC废催化剂脱除烟气中NO的过程。FCC废催化剂与本发明催化剂和活性炭按一定比例混合组成混合物；在流化床反应器内，烟气与该混合物接触进行反应，所含的NO被脱除。
摘要（英）：

The invention discloses a catalyst for removing NO in smoke and a preparation method thereof, and is used for solving the problems that the existing method for removing NO in the smoke by adopting an FCC (fluidized catalytic cracking) waste catalyst is low in NO removing rate, the conversion rate of NO is greatly reduced due to SO2 in the smoke, NH3 serving as a reducing agent has defect and the like. The catalyst disclosed by the invention comprises the following components by weight percent: 70-85% of Al2O3, 5-15% of CeO2, 3-15wt% of CuO and 50-350mu g/g of Pd. The invention discloses the preparation method of the catalyst. The catalyst disclosed by the invention can be mainly applied to a process for removing NO in the smoke by adopting the FCC waste catalyst. According to the invention, the FCC waste catalyst, the catalyst disclosed by the invention and activated carbon are mixed in a certain proportion to form a mixture; and in a fluidized bed reactor, the smoke is contacted with the mixture for reaction, thus contained NO is removed.
