Abstract:
A method of activating a molded Cu-ZSM5 zeolite adsorbent of the present invention includes: oxidizing a molded product of Cu-ZSM5 zeolite in the flow of air or a gas having an equivalent oxidizability to the air at a temperature of 250° C. to 550° C.; and then heat-treating the molded product of the Cu-ZSM5 zeolite in vacuum or the flow of an inert gas at a temperature of 550° C. to 800° C. According to the present invention, an adsorbent whose adsorption performance is not deteriorated can be obtained in the case where a molded product is produced using Cu-ZSM5 zeolite.
