초록

Spherocarb와 Sucrose Char에 의해 흡착된 질소가스의 양은 온도를 77K에서 184K가지 일정하게 유지시키면서, 상대적 압력의 함수로서 측정되었다 다른 온도에서의 Isotherm은 흡착제를 일정한 온도에서 유지시키면서, 액화질소, iso-펜탄, n-펜탄, 에틸알코올과 iso-프로필 알코올의 Slush bath를 사용하여 얻어졌다. 이 연구의 목적은 BET와 D-R같은 흡착모델을 사용하여, 실험적 데이타를 분석함으로써, 비표면적과 세공부피에 대한 정보를 얻는데 있다.

The amount of nitrogen gas adsorbed by Spherocarb and Sucrose Char was measured as a function of the relative pressure with temperature being kept constant at 77 to 184K. Isotherms at different temperatures were obtained by keeping the adsorbent at a constant temperature using liquid nitrogen, iso-pentane, n-pentane, ethyl alcohol, and iso-propyl alcohol slush baths. The objective for this study is to provide information on the specific surface area and pore volume by analyzing the experimental data using adsorption models such as the Brunauer-Emmett-Teller and Dubinin-Radushkevich models.
