Abstract:	Permeant concentrations in silicalite-filled silicone rubber membranes during pervaporation of propanol/water mixtures were measured using multi-layered membranes. Experimentally determined concentration profiles show that the propanol concentration in the silicalite-filled membrane increases with increasing silicalite content. The water concentration in the membrane is low and no water is present in the silicalite particles during pervaporation. The concentration profiles measured here support the observations from the resistance model that the diffusion through the membrane determines the transport rate, i.e., adsorption is a fast process.
