Publication number: 20240116033Abstract: The present invention relates to the technical field of catalyst preparation, disclosing a preparation method and application of a coated vanadium-tungsten-titanium oxide monolithic SCR catalyst. The method includes the steps of mixing a vanadium oxide precursor, a tungsten oxide precursor, titanium dioxide, an inorganic adhesive, an organic adhesive and a macromolecular surfactant with deionized water and stirring them to obtain a thick liquid; adding a pH adjuster to the thick liquid to make its pH 1.5-4.5; impregnating a cordierite honeycomb carrier in the thick liquid to obtain a preliminarily-impregnated catalyst and dried and calcined the preliminarily-impregnated catalyst to obtain a finished catalyst. The method has advantages such as simple operation, easy repetition and short time-consuming, so it can be applied to exhaust gas post-treatment of a marine diesel engine, and provide a good choice for catalysts used to denitrify medium and high temperature exhausted gas from marine engines.Type: ApplicationFiled: December 14, 2023Publication date: April 11, 2024Inventors: Mingyu GUO, Yidan HUANG, Boqun LIU, Shaoping CUI, Shipei DONG, Siqi CHEN, Bin LIU, Yingjie ZHAO, Fang LIN, Zhonghua TIAN, Junjie ZHAO, Wei YE, Yanjie WEI, Zhipeng ZHANG
