The invention discloses a preparation method of a zeolite hydrocarbon adsorption reforming catalyst, which comprises the following steps: mixing the molecular sieve with a metal salt solution, stirring for reaction, filtering, washing and drying to obtain the zeolite hydrocarbon adsorption reforming catalyst. The zeolite hydrocarbon adsorption reforming catalyst has lower adsorption temperature, catalytic temperature and higher desorption temperature for hydrocarbon pollutants, has good catalytic conversion effect for the hydrocarbon pollutants, greatly reduces the dependence on DOC and TWC catalysts, and enables motor vehicles to meet the emission requirements of the hydrocarbon pollutants. |
