Abstract:
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.
