ABSTRACT:
Molecular sieve agglomerates that can have improved physical and chemical properties are prepared by methods which comprise contacting the agglomerates with an alkali metal silicate solution. Molecular sieve agglomerates which comprise binders such as kaolin can additionally be contacted with an alkali hydroxide solution to convert the kaolin to Zeolite A prior to contacting the agglomerates with the alkali metal silicate solution to further improve properties. The molecular sieve agglomerates prepared according to the present invention are suitable for use as refrigerant desiccants.
