Abstract
The instant invention is directed to a process for selectively removing detrital material from boro-aluminosilicate selected from EUO, NES and intergrown mixtures of EUO and NES boro-aluminosilicate topology zeolites having a Si/M ratio of greater than about 50, comprising treating said boro-aluminosilicate with a base for a time and at a temperature sufficient to remove said detrital material from said boro-aluminosilicate wherein the concentration of said base is less than about 0.5 normal. Base concentrations in excess of this level may cause the removal of framework components leading to subsequent structural degradation.
