ABSTRACT:
The present disclosure relates to improved methods for the preparation of aluminum phosphate molecular sieves and faujasite-type zeolites having stably encapsulated multidentate metal chelate complexes. This is achieved through direct incorporation of a selected multidentate chelate complex into the molecular sieve or zeolite reaction admixture prior to crystallization, allowing the admixture to react under conditions appropriate for the selected molecular sieve or zeolite, followed by preparation of the resultant molecular sieve-metal chelate complex in a highly crystalline form.
