摘要
The alloy for producing filters for the prodn. of highly purified H2 by diffusion contains 43-89 wt.% Pd, 10-26% Ag, 1-26% Au, 0.1-0.9% Ru, 0.1-2% Al and 0.1-2.5% Pt. The alloy has very high permeability to H2, improved mechanical strength and high resistance to corrosion. Extra-pure H2 can be prepd. by diffusion through such filters from, e.g. a N2 + H2 mixt. with is not 75 vol. % H2 or from hydrocarbon conversion prods. contg. 40-60 vol. % H2.
