•SAPO-34 was synthesized via a dry gel method at high temperatures using morpholin as template.•The synthesized samples were identified to be SAPO-34 with high purity and crystallinity.•High temperature method reduced synthesis time to below 1 h.
SAPO-34 is one of the main catalysts used in the petrochemical industry. Various effective methods have been developed to synthesize SAPO-34 with optimal size and characteristics for such application. In the present study, SAPO-34 was synthesized using a dry gel method at high temperatures. Morpholine was used as an organic template. The products were characterized by X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, and gas sorption analysis. The results showed that application of the dry gel method at high temperatures successfully afforded a pure catalyst with high crystallinity. Small particles of less than 500 nm could be obtained within a short reaction time of 30 min.
