    摘要: A method for synthesizing small crystals of silicoaluminophosphate-34 (SAPO-34) molecular sieves with high structural purity. The method includes forming a first slurry and a second slurry which are aged separately to form a first aged slurry and a second aged slurry. The first slurry includes a first source of phosphorus, a first source of aluminium, a first source of silicon, and at least one first organic structure directing agent. The second slurry includes a second source of phosphorus, a second source of aluminium, a second source of silicon, and at least one second organic structure directing agent. Then, the first aged slurry and the second aged slurry are combined to form a mixture of aged slurries. Finally, crystallization of silicoaluminophosphate molecular sieves comprising the SAPO-34 molecular sieves is induced from the mixture of aged slurries.
