Abstract

일련의 알미늄함량을 달리하는 알미늄 추출 "제오라이트"에 대한 질소흡착등온선을 액체 질소 온도에서 구하고 "랑그미야" 및 "듀비닌-아스타코부"의 식에 의하여 해석하였다. 흡착점에는 두가지 종류가 있으며 알미늄 추출 "제오라이트"의 유효세공용적은 단위세포당 알미늄원자수가 35정도에서 극대치를 가지며 그의 실세공용적은 "제오라이트"의 결정구조가 파괴될때까지 증가한다. 또한 몇가지 알미늄함량의 다른 시료에 대하여 열저항성을 비교하였다.

The adsorption isotherms of nitrogen on the aluminium-extracted zeolites containing different aluminium contents in series were obtained at the temperature of liquid nitrogen and analysed by utilizing Langmuir's and Dubinin-Astakhov's equation.
These give rise to the conclusion that there are two types of adsorption site, and effective micropore volume of aluminium-extracted zeolites have a maximum value at about 35 aluminium atoms per unit cell but real volumes of the solids increase linearly with decreasing aluminium atom until the corruption of zeolite crystal structure is reached.
The properties of thermal resistance for some aluminium-extracted zeolites were compared to one another.
