Dlouhodobá stabilita zeolitických MFI membrán

Abstract

The aim of the study is to monitor zeolite membrane flux and separation factor as a function of total molar amount fed to the zeolite membrane surface area. The flux of permeating components (n-butane, isobutane) was reduced by factor of 1.6 for n-butane and 2.3 for isobutane. Ideal separation factor increased from 16 to 26 with increasing total molar amount of butane isomers fed to the membrane
