Investigation of high pressure permeation behaviour of single gases through microporous ceramic membranes Part 1. Measurement method and influence of adsorption on permeationThe permeation behaviour of single gases (He, H 2 , N 2 , Ar, CH 4 , CO 2 ) through meso (ZrO 2 ) and micro (TiO 2 ) porous ceramic membranes was measured within a pressure range of 1 to 10 MPa and a temperature range of 293 to 373 K, using steady state and dynamic experimental methods. The TiO 2 -membrane shows by adsorption affected permeation, whereas the ZrO 2 -membrane is not influenced by these effects.
