The present invention relates to a hydrocarbon adsorbent with metal-impregnated zeolite particles having regular mesopores and a manufacturing method therefor. The hydrocarbon adsorbent in which zeolite particles having 2-10 nm sized mesopores regularly formed therein are impregnated with metal cations and metal oxides according to the present invention have regular mesopores and can be controlledwith regard to Si/Al ratio and mesoporosity. Thus, the hydrocarbon adsorbent shows increased adsorption capacity for hydrocarbons in a cold start section and can rapidly oxidize the hydrocarbons upondesorption thereof, thereby reducing the discharge of exhaust gas produced in automobiles and industries. 本发明涉及一种包括具有规则介孔的金属浸渍的沸石颗粒的烃吸附剂及其制备方法。烃吸附剂具有规则的介孔并且相对于Si/Al比和介孔隙可以进行控制，在所述烃吸附剂中，具有其中规则地形成的2-10nm尺寸的介孔的沸石颗粒浸渍有根据本发明的金属阳离子和金属氧化物。因此，烃吸附剂在冷启动部分中显示对烃的增加的吸附能力，并且可以在其解吸时迅速氧化烃，从而减少在汽车和工业中产生的废气的排放。
