Abstract

Adsorption capacities of zeolites are rapidly determined by a vapor sorption apparatus which can be used as an ultramicroporosimeter. From the sorption data, it is possible to calculate the zeolite affinities toward various adsorbates in comparison with water. The n-hexane affinity index of the new ZSM zeolites has values always higher than those of X, Y or Zeolon zeolites. This fact is attributed to the unusual framework structure of the silica-rich ZSM zeolites.

Abstract

Адсорбционная емкость цеолитов была быстро определена с помощью аппарата паровой сорбции, который может быть использован в качестве ультрамикропорозиметра. Из сорбционных данных можно определить сродство цеолитов к различным адсорбатам по сравнению с водой. Фактор сродства н-гексана новых ZSM цеолитов всегда выше, чем для X, Y или Цеолон цеолитов. Этот факт приписывается необычной сетчатой структуре ZSM цеолитов, богатых кремнием.
