Process for the synthesis of silicoaluminophosphate molecular sieves |
摘要 |
The invention is directed to a method for making a silicoaluminophosphate (SAPO) molecular sieve from a reaction mixture comprising components present in amounts sufficient to form the SAPO, the reaction mixture having a first pH. The method comprises the steps of: adding an acid to the reaction mixture after the reaction mixture undergoes a change in pH from the first pH; and crystallizing the SAPO from the reaction mixture. The present invention is also directed to a silicoaluminophosphate molecular sieve made by this process. |
