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, having a high alumina-to-silica ratio, with additional occluded non-zeolitic silicate, and solid particulate alumina is the source of alumina in the zeolite.
