Abstract

The texture and adsorption properties of a natural, Hungarian mordenite were investigated by electron microscopy and BET adsorption measurements. The properties of the ion-exchanged adsorbents were characterized by CO2 and SO2 isotherms. The measurements were evaluated on the basis of the pore-filling theory of Dubinin. We have found that at 20°C the H+-form of mordenite interacts preferably with CO2, while on the Na+- and Ca2+-derivatives stronger adsorption of SO2 takes place. This fact accounts for their applicability as selective adsorbents.

Abstract

Исследованы текстура и адсорбционные свойства природного, отечественного морденита методами электронной микроскопии и БЭТ адсорбции. Свойства ионнообмененных адсорбентов были охарактеризованы изотермами CO2 и SO2. Результаты измерений были обработаны на основе теории заполнения пор Дубинина. Было найдено, что при 20°C H+-форма морденита взаимодействует преимущественно с CO2, а на Na+- и Ca2+-формах SO2 адсорбируется более прочно. Этот факт объясняет применяемость данного цеолита в качестве селективного адсорбента.
