Dlouhodobá stabilita zeolitických MFI membrán
 Hrabánek, Pavel ; Zikánová, Arlette ; Bernauer, B. ; Fíla, V. ; Brabec, Libor ; Šolcová, Olga ; Kočiřík, Milan
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.

Separace izomerů butanu použitím silikalitové kompositní membrány
 Hrabánek, Pavel ; Zikánová, Arlette ; Bernauer, B. ; Fíla, V. ; Kočiřík, Milan
Separation efficiency of the ceramic silicalite-1 composite membranes was studied with single component and equimolar mixture of butane isomers as a function of operating conditions (feed pressure, permeation temperature) using permeation apparatus MEMFIS. The separation factor for butane in the mixture with isobutane ranged between 10 and 20, which is an indication of high membrane quality. The flux of n-butane flux as a function of permeation temperature showed a maximum at 423 K.
