Abstract:
Strengthened zeolite molecular sieve agglomerates are prepared by treating the agglomerates with an aqueous solution of a water soluble silicon compound and subsequently with an aqueous solution of a mineral acid of sufficient strength to decationize the molecular sieve and/or increase its SiO.sub.2 :Al.sub.2 O.sub.3 ratio. The strengthened agglomerates are suitable for use as catalyst supports.
