## Abstract Permeation of binary gaseous mixtures through a silicaliteβ1 membrane was studied. Results are reported for the fluxes and separation factors as a function of the feed composition, the pressure and the temperature. For the various cases a comparison is made between the binary and the si

β¦ Synopsis
The permeation behaviour of single component and binary mixtures of hydrogen, n-butane and carbon dioxide through a silicalite-1 membrane as a function of temperature (steady state) and time (transient) are presented. Multicomponent permeation can be well described by the Generalized Maxwell-Stefan equations.

Single-component permeation data are given for methane, ethane, propane, ethene and propene through a silicalite-1 membrane of approximately \(40 \mu \mathrm{m}\) thickness at \(293 \mathrm{~K}\) as a function of their partial pressure. The permeation fluxes generally decrease with increasing molecu
Results are reported for the one-component permeation of a number of gases through a silicalite-1 membrane. The effect of several operating conditions, like the temperature, the feed pressure, the sweep gas flow rate, and the orientation of the membrane, on the flux are discussed. The optimal experi
