초록

석탄을 원료로 하는 탄화 시료로 분자체 특성을 지닌 탄소 흡착제를 제조하였다. 변형제를 사용하여 탄소 분자체를 만들었으며, 변형제 농도 변화에 따른 분자체 특성에 관해 연구하였다. 그리고 탄소 분자체의 성능을 측정키 위해 산소와 질소가스를 사용하였으며, Cahn microbalance(D-200)를 사용하여 탄소 흡착제의 흡착 속도를 측정하였다. 이 실험치를 흡착 속도식에 대입하여 탄소 분자체에 따른 가스의 확산도를 구하였으며, 분자체 성능에 대한 변형제 분자량과 농도의 영향을 나타내었다.

Carbon adsorbents, having the properties of molecular sieve, were prepared based on coat materials. A couple of modifiers were used to prepare carbon molecular sieve. The effects of modifier concentrations on the characteristics of carbon molecular sieve were investigated. In order to verify the characteristics of carbon molecular sieve, the adsorption rates of oxygen and nitrogen gases on the carbon molecular sieve were measured using Cahn microbalance(model # D-200). The experimental data were fitted to an adsorption rate equation and gas diffusivities were calculated. The effects of modifier molecular weight and concentration on the characteristics of carbon molecular sieve were shown.
