Název v původním jazyce

Gas Phase Transport, Adsorption and Surface Diffusion in Porous Glass Membrane

Popis výsledku v původním jazyce

Due to their improved performance and excellent chemical resistance there is a growing interest in applying inorganic membrane not only for gas separation but also in combination with heterogeneous catalysts in membrane reactors. The objective of this work is to study the mass transfer through a Vycor glass membrane which might be applied successfully in membrane reactors. Transient diffusion experiments were carried out in which two different gases were exchanged via the membrane. If adsorbable gases are involved there is a strong asymmetry between corresponding exchange experiments. In order to analyze the transient diffusion experiments a transport model was applied which is based on the Dusty Gas Model for the quantification of gas phase transportand on the generalized Stefan-Maxwell theory for the description of the transport of adsorbed species. The model describes relatively well exchange experiments performed with H2 and N2 or He and CO2.
