An Improved Method for the Synthesis of SAPO-41

Abstract:

A medium molecular sieve SAPO-41 was synthesized by gradual heating of the synthesis gel to obtain highly crystalline material within 36 h. The samples were characterized by XRD, SEM, MAS NMR and NH3-TPD. The samples synthesized by gradual heating method can be introduced more silicon, and have more mid and strong acid sites than the conventional ones. The particles of the samples synthesized by this method were more uniform in size and morphology than the ones synthesized conventionally.
