Abstract

Disclosed is a method for the manufacture of silicoaluminophosphate (SAPO) and/or aluminophosphate (ALPO) molecular sieves. The method includes maintaining the slurry of the as crystallized molecular sieve under substantially static conditions when stored after substantially complete crystallization and prior to recovery of the product.
