Hydrocarbon gases permeation properties through amorphous silica membrane via sol–gel method was reviewed. Pore size tuning for the formation of loose structure in comparison with conventional dense silica membranes was possible to apply for propylene/propane separation system. Here, effect of membrane fabrication parameter such as calcination temperature, cation, and anion doping into silica structure on propylene/propane permeation and adsorption properties was introduced.
