Beschreibung
Zusammenfassung:	The present invention relates to a hydrocarbon adsorption and desorption composite which reduces hydrocarbon emissions from vehicle exhaust gas and improves the hydrothermal stability of a device and a manufacturing method thereof. In the hydrocarbon adsorption and desorption composite, metal ions are bound to a gas adsorption unit comprising aluminum to improve hydrocarbon adsorption capacity, and a reinforcing unit made of silica is formed on a surface of the gas adsorption unit to improve hydrothermal stability. 본 발명은 자동차 배기가스에서 나오는 탄화수소 배출을 저감시키고 장치의 수열 안정성을 향상시키는 탄화수소 흡탈착 복합체 및 이의 제조방법에 관한 것으로, 탄화수소 흡탈착 복합체는 알루미늄을 포함하는 가스흡착부에 금속 이온이 결합하여 탄화수소의 흡착능이 향상되고, 상기 가스흡착부의 표면에 실리카로 이루어진 보강부가 형성되어 수열 안정성이 향상될 수 있다.
