A thin layer of silica will be deposited on Vycor glass by CVD                  using the oxidation reaction of silane.  The CVD reaction                       is highly pore-diffusion limited, so the deposition only occurs                 at the pore mouths.  The depth of deposition can be controlled by               adjusting the temperature and pressure.  From the literature data               on the rate of this reaction, a film of approximately 1 micron                  can be deposited at 300 C at 0.5-5 Torr pressure.  The                          diffusivities of hydrogen and other gases through the composite                 membrane will be measured.  Further, several equilibrium-limited                reactions, in which hydrogen is a product, will be carried out in               a tube formed by the composite membrane, in order to test the                   feasibility of the idea of reactor/separator.                                                                                                                   Success of the experiments could lead to the production of high                 temperature gas separation membranes and the possibility of a                   combined reactor-separator.
