METHOD FOR PREPARING CRYSTALLINE METALLOALUMINOPHOSPHATE (MeAPO) MOLECULAR SIEVE FROM AMORPHOUS MATERIALS |
摘要 |
A process for obtaining a metalloaluminophosphate (MeAPO) molecular sieve comprising the following steps in the order given: a), providing an aqueous solution containing sources of at least 2 of the following: Metals (Me), Al and P; b). co-precipitating an amorphous precursor of the molecular sieve from the solution by changing the solution's pH, followed by separating the amorphous precursor from the water, optionally including formulation; c). optionally washing and drying at a temperature below 45O°C of the amorphous precursor; d). contacting the amorphous precursor with a template-containing aqueous solution and with a source of Al, P or Me, which is not already present in step (a) and optionally additional sources of Al and/or P and/or Me; and e). partially crystallising the molecular sieve under autogeneous conditions so that 5 to 90% by weight of the amorphous precursor crystallises. |
