  • Hybrid silica membrane for water removal from lower alcohols and hydrogen separation
    Patent number: 8709254
    Abstract: A microporous organic-inorganic hybrid membrane based on silica of the invention has an average pore diameter of less than 0.6 nm, and comprises bridging organosilane moieties of the formula ?O1.5Si—CHR—SiO1.5? or ?O1.5Si—CH(CH3)—SiO1.5?. The membrane can be used in the separation of hydrogen from mixtures comprising hydrogen and CH4, CO2, CO, N2, and the like, and in the separation of water from alcohols having 1-3 carbon atoms, optionally in the presence of an inorganic or organic acid.
    Type: Grant
    Filed: July 14, 2009
    Date of Patent: April 29, 2014
    Assignee: Stichting Energieonderzoek Centrum Nederland
    Inventors: Rob Kreiter, Hessel Lennart Castricum, Jaap Ferdinand Vente, Johan Evert Ten Elshof, Maria Dirkje Anna Rietkerk, Henk Martin Veen
