Abstract
This invention relates to zeolitic molecular sieve compositions characterized by outstanding capability to complex multivalent cations, especially calcium. In particular, the invention relates to novel zeolitic molecular sieve compositions, especially those based on molecular sieves having a high alumina-to-silica ratio, in which crystals of the zeolite are modified by the inclusion of occluded silicate.
