Patent ID: 7977273

Claim:
A process for preparing a metallo-aluminophosphate molecular sieve comprising: a) first providing a reaction mixture comprising a quantity of metallo-aluminophosphate seeds containing from about 5 to 20 wt-% metal oxide on a dry oxide basis, a source of aluminum, a source of phosphorus, at least one organic template, and, a source of metal; b) inducing formation of crystals of said metallo-aluminophosphate molecular sieve from the reaction mixture; and c) separating said crystallized metallo-aluminophosphate molecular sieve, wherein said metallo-aluminophosphate molecular sieve has a roughly rectangular parallelepiped crystal morphology or intergrowth of roughly rectangular parallelepiped crystal morphologies or a mixture thereof, wherein said reaction mixture excluding said metallo-aluminophosphate seeds comprises between about 1 to 5 wt-% silica.
