초록

대기 중 $CO_2$ 포집 기술은 비점오염원 배출 $CO_2$를 포집할 수 있는 유일한 기술 중 하나이다. 본 논문에서는 저농도 $CO_2$를 이용한 흡착 실험을 수행하였다. 세 종류의 흡착제를 이용한 흡착과 열재생을 반복하는 실험을 수행한 결과 제올라이트 5A, 13X 그리고 활성탄의 $CO_2$ 흡착량은 21 mg/g, 12 mg/g 그리고 6 mg/g으로 나타났으며, 열재생 반복실험 결과에서 제올라이트 5A가 가장 우수한 흡착 성능을 보여주었다.

Direct Air Capture (DAC) technology using reusable energy is a plausible process to capture $CO_2$ from non-point sources. In this paper, adsorption and desorption were repeatedly tested using low concentration $CO_2$. Three types of adsorbents were examined in cyclic $CO_2$ adsorption and thermal regeneration. Adsorption capacities of zeolite 5A, zeolite 13X and activated carbon were 21 mg/g, 12 mg/g and 6 mg/g, respectively. Zeolite 5A shows the highest adsorption capacities after cyclic thermal regeneration.
