Title: The Innovative Contributions of Xi Feng
Introduction
Xi Feng is a notable inventor based in Chengdu, China. He has made significant contributions to the field of catalysis, particularly in the development of molecular sieve catalysts. With a total of 2 patents, his work has garnered attention for its innovative approaches and practical applications.
Latest Patents
Xi Feng's latest patents include a method for preparing a molecular sieve SCR catalyst and the catalyst prepared through this method. The first patent describes a process where several molecular sieves are mixed and modified using transition or rare-earth metals via ion exchange. This is followed by the loading of iron through equivalent-volume impregnation and copper through one or more liquid ion exchanges. The resulting catalyst material is then coated on a carrier substrate, creating an integral catalyst. His second patent focuses on an AFI-CHA hybrid crystal molecular sieve and an NH3-SCR catalyst that utilizes this hybrid crystal as a carrier. This innovative molecular sieve combines AFI-type SAPO-5 and CHA-type SAPO-34 molecular sieves, synthesized through hydrothermal methods, which significantly enhance the catalytic activity and hydrothermal stability of the catalyst.
