Abstract
The effect of water adsorption on the permeation properties of MFI-type membranes, permeation tests were conducted using the membranes dried at room temperature after soaking them in deionized water. The separation factor of n-C4H10/H2 measured during cooking was less than that observed during cooling. The observed difference in the permeances during heating and cooling was due to the desorption of water adsorbed in the membrane. The permeances measured during cooling were higher than those in the micropore of zeolite during heating up to 300°C. The desorption of water was attributed to the larger permeances measured during cooling as compared with those obtained during heating.
