Hydrogen Production via a Commercially Ready Inorganic Membrane Reactor, Semiannual Report: October 2003 - March 2004

PDF Version Also Available for Download.

Description

The porous stainless steel substrate commercially available from Pall offers great potential for large-scale membrane based high temperature gas separations. Our proposed project involves the deposition of the M&P carbon molecular sieve-based hydrogen membrane on AccuSep substrate as a membrane to reactor water-gas-shift reaction. However, the AccuSep substrate was originally designed for liquid phase applications . During the 1st half, this commercial substrate has been modified and improved with regard to its surface topography and end seals. The substrate is now suitable for the deposition of the CMS membrane for hydrogen separation according to the characterization we preformed. In addition, ... continued below

Description

The porous stainless steel substrate commercially available from Pall offers great potential for large-scale membrane based high temperature gas separations. Our proposed project involves the deposition of the M&P carbon molecular sieve-based hydrogen membrane on AccuSep substrate as a membrane to reactor water-gas-shift reaction. However, the AccuSep substrate was originally designed for liquid phase applications . During the 1st half, this commercial substrate has been modified and improved with regard to its surface topography and end seals. The substrate is now suitable for the deposition of the CMS membrane for hydrogen separation according to the characterization we preformed. In addition, 40{angstrom} Al{sub 2}O{sub 3} membrane layers have been deposited on the improved AccuSep substrate successfully. The SEM, EDX and pore size distribution analysis indicate that the 40{angstrom} membrane is extremely thin, and defect free with a narrow pore size distribution around 40{angstrom} primarily. As the above results suggest, we have made significant progress in preparing a high quality nominal 40{angstrom} (actually 50{angstrom}) layer on the Pall substrate. During the 2nd half of Year 1, we will (1) continue this development work with a focus on eliminating the high pore size peak and (2) begin the CMS layer deposition on the 40{angstrom} deposited AccuSep.
