Abstract: Disclosed are a hydrocarbon adsorption and desorption complex showing hydrocarbon adsorption and oxidation performance by controlling the cation ratio in zeolite, and a preparation method therefor. The hydrocarbon adsorption and desorption complex controls a cation ratio to exhibit the excellent hydrocarbon adsorption ability and oxidation performance even at a temperature lower than the catalyst activation temperature, and increases hydrothermal stability of the hydrocarbon adsorption and desorption complex through hydrothermal treatment to exhibit the excellent hydrocarbon adsorption and desorption performance even in a situation where water is present at a high temperature.

Abstract: A catalyst for adsorbing hydrocarbon includes a first catalyst configured to adsorb short-chain hydrocarbons and including zeolites having a pore size of about 0.30 nm to about 0.44 nm and a second catalyst configured to adsorb a long-chain hydrocarbon and including zeolites ion-exchanged with a transition metal. The catalyst can be coated on a substrate of a hydrocarbon trap.
