Abstract

Process improvements in silica membrane fabrication, especially the use of clean-room techniques, resulted in silica membranes without detectable mesoscopic defects, resulting in significantly improved transport properties. Supported membranes calcined at 400°C were 30 nanometers in thickness, showed a H 2 permeance at 200°C of 2 × 10 −6 moles per square meter per second per Pascal (mol m −2 s −1 Pa −1 ), and had a CH 4 permeance more than 500 times smaller. Molecules larger than CH 4 were completely blocked. Silica membranes calcined at 600°C showed no detectable CH 4 flux, with a H 2 permeance of 5 × 10 −7 (mol m −2 s −1 Pa −1 ) at 200°C. These results signify an important step toward the industrial application of these membranes such as purification of H 2 and natural gas as well as the selective removal of CO 2 .

The ability to directly calculate separation performance from J is supported by the fact the membrane's silica material showed Henri-type adsorption behavior at the gas pressures and temperatures considered here (8).
