| Permeation of single gases in thin zeolite MFI membranes (1998) | |||||||||
Abstract | |||||||||
| The permeation of a series of gases with widely different Lennard-Jones kinetic diameters and sorption properties is investigated as a function of feed pressure (up to 100 kPa) and temperature (298–473 K) with two different methods. The membrane system studied consists of an MFI (silicalite) top-layer (thickness 3 μm) directly grown on an -alumina support. Flux values of molecules with a kinetic diameter, dk, | |||||||||
