Membranes and membrane reactors for pure hydrogen production are widely investigated
not only because of the important application areas of hydrogen, but especially because …

2. BACKGROUND TO GASIFICATION Gasification can be described as the “conversion of
any carbonaceous feedstock into a gaseous product with a useful chemical heating value.” 7 …

Today, electricity & heat generation, transportation, and industrial sectors together produce
more than 80% of energy-related CO 2 emissions. Hydrogen may be used as an energy …

Hydrogen-selective membranes formed from body centred cubic alloys can exhibit very high
hydrogen permeability, but are prone to brittle failure due to excessive hydrogen absorption …

Composite membranes were fabricated by sputtering 100 nm of Pd on to both sides of
dense BCC metal foils (V, Ta, Nb). Under pure H 2 gas testing at 500° C the maximum …

VB-group-based ternary alloys membranes for hydrogen separation have attracted great
attention because of their superiorities on selectivity and permeability of hydrogen. However …

Abstract Nb-Hf-Co alloys, consisting of a multi-phase microstructure with primary BCC-(Nb,
Hf) and eutectic {BCC-(Nb, Hf)+ HfCo} phases, are a potential alloys for hydrogen …

Vanadium is highly permeable to hydrogen which makes it one of the leading alternatives to
Pd alloys for hydrogen-selective alloy membrane applications. The tendency of vanadium to …

Vanadium and other group V metals and alloys exhibit much higher hydrogen permeabilities
than palladium alloys, and the basis of this lies primarily in their high hydrogen solubility …

The structural properties and hydrogen permeation characteristics of ternary vanadium–iron–
aluminum (V–Fe–Al) alloy were investigated. To achieve not only high hydrogen …
