ARGON/OXYGEN SELECTIVE X-ZEOLITE
Application 91/MAS/2002 published 2007-03-30, filed 2002-02-06
An AgX-type zeolite having a silver exchange level of 20-70% and a Ar/O2 Henry's law selectivity ratio at 23°C of 1.05 or greater has an optimum combination of selectivity for argon over oxygen at lower cost than higher silver exchange levels. This material can be used in oxygen VSA/PSA processes to produce oxygen at purities above 97%.
