摘要： Provided herein are a method for producing a hydrocarbon adsorption catalyst includes dealuminated zeolite by heat-treating a zeolite in moisture-containing air at a first temperature to remove a portion of aluminum included in the zeolite, and supporting a metal on a carrier including the zeolite after the heat-treating and a hydrocarbon adsorption catalyst prepared using the same method. The metal-supported support may be additionally heat-treated in moisture-containing air at a second temperature that is higher than the first temperature.

摘要： The present invention relates to a hydrocarbon adsorbent with metal-impregnated zeolite particles having regular mesopores and a manufacturing method therefor. The hydrocarbon adsorbent includes a metal cation and a metal oxide that are impregnated in zeolite particles, in particular, the zeolite particles include regularly formed mesopores having a size of 2 to 10. By adjusting a Si/Al ratio and mesoporosity of the mesopores, a hydrocarbon adsorbent may have increased adsorption capacity for hydrocarbons in a cold-start section and can rapidly oxidize the hydrocarbon upon desorption thereof, thereby reducing the discharge of exhaust gas produced in automobiles and industries.
