Dichlorodifluoromethane중에 함유되어 있는 미량의 수분을 선택 흡착하는데 화과적인 흡착제를 검토하기 위해 제올라이트 A와 활성알루미나상에서 물의 흡착및 탈착특성과 파과곡선을 측정·연구 하였다. 가스크로마토그라프에 의해에서 저압영역에서 흡착등온선과 승온 열탈착곡선을 구하였으며 이로부터 구한 파과곡선으로부터 분자여과작용을 하는 제올라이트 A가 활성알루미나보다 dichlorodifluoromethane중에 함유된 수분의 분리효과가 좋음을 알았다. CaA가 NaA보다 흡착용량은 컸으며 에서는 NaA가 더 용이한 것을 확인하였다.

The adsorption and desorption properties of water and breakthrough curves of dichlorodifluoromethane-water system were measured on zeolite NaA, CaA, and activated alumina to see the adsorption characteristics, which are effective for the separation of water from dichlorodifluoromethane-water mixture gas. The adsorption isotherms at low equilibrium pressure and the temperature programmed desorption curves of water were measured by gas chromatography. The separation of water from dichlorodifluoromethane on molecular sieving zeolite A has been found to be more effective than on activated alumina by comparing breakthrough curves which were determined from the measured isotherms. It may be ascertained that NaA is the most effective adsorbent from a standpoint of the regeneration by desorption process, although CaA adsorbs water more than NaA.
