High permselectivities of microporous silica-modified γ-alumina membranes
A microporous silica-modified gamma-alumina membrane can be made through a sol-gel process. A very thin layer of microporous silica (about 30 nm) is present on top of the gamma-alumina membrane. This layer exhibits very good permselectivities towards CO2-CH4 and hydrocarbon-inert gas mixtures, with...

Zusammenfassung: | A microporous silica-modified gamma-alumina membrane can be made through a sol-gel process. A very thin layer of microporous silica (about 30 nm) is present on top of the gamma-alumina membrane. This layer exhibits very good permselectivities towards CO2-CH4 and hydrocarbon-inert gas mixtures, with relatively high permeabilities. It is expected that selective separation with high fluxes can be realised with this membrane. 10 refs. |
