ABSTRACT:
There is provided a three-step method for removing the residue of an organic directing agent from as-synthesized zeolites. The first step involves contacting the as-synthesized zeolite with an aqueous solution of a fluorosilicate salt such as ammonium fluorosilicate. The second step involves ion-exchanging the zeolite with an alkali metal or alkaline earth metal salt such as KCl. The third step involves calcining the ion-exchanged zeolite. This method is particularly useful for removing the residue of an organic directing agent from ZSM-18.
