Description:
No 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 V 99 Y 1 alloy membrane are presented. Hydrogen permeation experiments have been performed to investigate the hydrogen transport properties through the Pd-coated V 99 Y 1 alloy membrane in the pressure range of 1.5–3.0 bar under pure hydrogen as well as H 2 -CO 2 and H 2 -CO gas mixtures at 400 °C. The maximum hydrogen permeation rate was ∼32 mL min –1 cm –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. Synthesis, hydrogen permeation properties, and chemical stability of a novel Pd-coated V 99 Y 1 alloy membrane are described. The hydrogen flux values obtained for this new V-based alloy membrane under present conditions are higher than for pure palladium. The results open up new directions in the synthesis of novel non-Pd-based metal membranes for hydrogen separation in precombustion capture applications.
