ABSTRACT:
A process for manufacturing a metalloaluminophosphate molecular sieve, the process comprising the steps of: (a) combining at least one silicon source, at least one metal source, at least one structure-directing-agent (R), at least one phosphorus source, and at least one aluminum source to form a mixture having a molar composition according to formula:in-line-formulae description="In-line Formulae" end="lead"?(n)Si:Al2:(m)P:(x)R:(y)H2O:(z)Min-line-formulae description="In-line Formulae" end="tail"?wherein n is in the range of from about 0.005 to about 0.6, m is in the range of from about 1.2 to about 2.4, x is in the range of from about 0.5 to about 2, y is in the range of from about 10 to about 60, and z is in the range of from about 0.001 to 1; and (b) submitting the mixture to crystallization conditions to form the metalloaluminophosphate molecular sieve, wherein the metalloaluminophosphate molecular sieve has an X-ray diffraction pattern having a FWHM greater than 0.10 degree (2θ) and an AEI/CHA framework type ratio of from about 0/100 to about 40/60 as determined by DIFFaX analysis.
