Abstract
AbstractNo investigation has yet been accomplished to screen the yttrium‐doped effects on vanadium‐based metal membranes. Synthesis, hydrogen permeation properties, and chemical stability of a novel palladium (Pd)‐coated V99Y1 alloy membrane are presented. Hydrogen permeation experiments have been performed to investigate the hydrogen transport properties through the Pd‐coated V99Y1 alloy membrane in the pressure range of 1.5–3.0 bar under pure hydrogen as well as H2‐CO2 and H2‐CO gas mixtures at 400 °C. The maximum hydrogen permeation rate was ∼32 mL min–1cm–2 for a 0.5 mm thick membrane under pure hydrogen. The results offer new directions in the synthesis of novel non‐Pd‐based metal membranes for hydrogen separation in precombustion capture applications.
