Publication number: 20230191362Abstract: 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.Type: ApplicationFiled: February 3, 2023Publication date: June 22, 2023Inventors: Jungkyu Choi, Kwan Young Lee, Eun-Hee Jang, Chang Hwan Kim, Chun Yong Kang
