Title: Fabrication and operational considerations of hydrogen permeable Mo₂C/V metal membranes and improvement with application of Pd

Abstract

Mo₂C has previously been demonstrated as an effective catalyst layer to enable stable H₂ permeation through vanadium foils at high temperatures. Here, in this paper, this approach was extended to several group V metal foils (V, Nb, and Ta) as well as mixed gas testing. The best permeability was achieved with V, and an activation process was developed to recover the performance of V foils displaying evidence of oxidation. Nb foils yielded ~20% the permeability of V, while Ta was too brittle to operate effectively. Mo₂C/V membranes were operated at feed conditions well above the ductile-to-brittle transition pressure without embrittlement; however, the H₂ permeability of Mo₂C/V membranes was significantly attenuated at lower temperatures (< 600 °C). H₂ permeation was also severely inhibited by the presence of N₂ or CO₂ in mixed gas environments due to strong competitive adsorption. The addition of a Pd catalyst layer on top of Mo₂C improved mixed gas stability and increased H₂ permeability to 2 × 10^-8 mol·m^-1·s^-1·Pa^-0.5 at 500 °C for V based membranes. Lastly, as an interlayer, Mo₂C was demonstrated to be a stable barrier preventing Pd-V interdiffusion at 500 °C while simultaneously allowing significant H₂ permeation.

Experimental and Theoretical Insights into the Potential of V₂O₃ Surface Coatings for Hydrogen Permeable Vanadium Membranes

Journal Article Fuerst, Thomas F. ; Petsalis, Elias P. ; Lundin, Sean-Thomas B. ; ... - Journal of Physical Chemistry. C

A grand challenge of vanadium-based H₂ permeable membranes is the development of effective, cheap, and stable catalysts to facilitate H₂ dissociation and recombination. This article investigates a facile air treatment to form catalytically active vanadium oxide on the surfaces of dense vanadium foils. The treatment consisted of short air exposure followed by H₂ reduction at 823 K, which produced a well-faceted and nanocrystalline V₂O₃ layer on the foil surfaces. The resulting membranes display stable H₂ permeability of 2 ± 0.25 × 10^-8 mol·m^-1·s^-1·Pa^-0.5, but transient declines in permeation are observed when operated at both elevated and reduced temperatures.

Nanoporous, Metal Carbide, Surface Diffusion Membranes for High Temperature Hydrogen Separations

Technical Report Way, J. Douglas ; Wolden, Colin A.

Colorado School of Mines (CSM) developed high temperature, hydrogen permeable membranes that contain no platinum group metals with the goal of separating hydrogen from gas mixtures representative of gasification of carbon feedstocks such as coal or biomass in order to meet DOE NETL 2015 hydrogen membrane performance targets. We employed a dual synthesis strategy centered on transition metal carbides. In the first approach, novel, high temperature, surface diffusion membranes based on nanoporous Mo₂C were fabricated on ceramic supports. These were produced in a two step process that consisted of molybdenum oxide deposition followed by thermal carburization. Our best Mo₂C surfacemore »« less

Influence of surface coating on the performance of V-Cu, V-Ti, and Ta membranes for hydrogen separation

Foils of V{sub 0.95}Ti{sub 0.05}, V{sub 1-x}Cu{sub x} (x = 0.01-0.12, atom fraction) and Ta coated with thin films of Pd or Pd alloys (Pd-Cu or Pd-Ag), and other metal interlayers were fabricated and tested for hydrogen permeability and stability at temperatures from 320-450 C. Vanadium-alloy or Ta foils were ion-milled and coatings between 30 and 250 nm thick were applied to both sides in-situ via electron beam evaporation. Membranes were between 40 and 75 {mu}m thick and were completely permselective for hydrogen. Pt or Ni surface coatings on VTi{sub 5} foils reduced the permeability by at least an ordermore »« less

WATER-GAS SHIFT WITH INTEGRATED HYDROGEN SEPARATION PROCESS

Technical Report Maria Flytzani-Stephanopoulos, PI ; Jerry Meldon, Co-PI ; Qi, Xiaomei

Optimization of the water-gas shift (WGS) reaction system for hydrogen production for fuel cells is of particular interest to the energy industry. To this end, it is desirable to couple the WGS reaction to hydrogen separation using a semi-permeable membrane, with both processes carried out at high temperatures to improve reaction kinetics and permeation. Reduced equilibrium conversion of the WGS reaction at high temperatures is overcome by product H{sub 2} removal via the membrane. This project involves fundamental research and development of novel cerium oxide-based catalysts for the water-gas-shift reaction and the integration of these catalysts with Pd-alloy H{sub 2}-separationmore »« less
