摘要:
To improve the column dynamics of commercial pelleted sodium aluminosilicate zeolite adsorbents used in gas separation, the pellets are treated by washing in dilute aqueous mineral acid. The treatment is most effective as applied to sodium mordenite pellets, employing hydrochloric acid of about 0.1 normality.
