  • Integrated catalyst system for stoichiometric-burn natural gas vehicles and preparation method therefor
    Patent number: 11731119
    Abstract: Disclosed in the present invention is an integrated catalyst system for stoichiometric-burn natural gas vehicles, the catalyst system consisting of a three-way catalyst, a molecular sieve catalyst, and a base body, the three-way catalyst and the molecular sieve catalyst being coated on a surface of the base body. In the integrated three-way catalyst and molecular sieve catalyst system of the present invention, at the same time that pollutants such as CO, HC, and NOx in the exhaust of stoichiometric-burn natural gas vehicles are processed, the produced byproduct NH3 can also be processed, and the conversion rates of CO, HC, NOx, and NH3 are high.

  • Method for preparing molecular sieve SCR catalyst, and catalyst prepared therethrough
    Patent number: 11673128
    Abstract: A method for preparing a molecular sieve SCR (selective catalytic reduction) catalyst and a prepared catalyst therethrough. In the method, several molecular sieves are mixed and modified by transition metal or rare-earth metal via ion exchange, then loaded Fe by equivalent-volume impregnation, and loaded Cu by one or more liquid ion exchange. This present invention, combined with several techniques, such as modification of stable molecular sieve by transition and rare-earth metal, Fe loading by equivalent-volume impregnation and Cu loading by one or more liquid ion exchange, and after through stable and effective modification and loading control, the obtained catalyst material is coated on a carrier substrate via size mixing and coating process to be prepared into an integral catalyst.
