| Outline of Final Research Achievements |
A silylated ionic liquid-derived organosilica membrane was prepared on the outer surface of a porous alumina substrate. Its separation properties for binary methanol/H2 and H2O/H2 mixtures, and a methanol/H2O/H2/CO2 quaternary mixture were studied. The separation factors for methanol/H2 in the binary system were 12-71. The membrane also showed high H2O/H2 separation performances in the quaternary system, and the presence of H2O and CO2 in the feed stream did not affect the methanol permeation performance. The silylated ionic liquid-derived organosilica membrane showed an excellent potential for the simultaneous separation of methanol and H2O from methanol synthesis gas.
