The flake structure SAPO-34 was firstly synthesized via a hydrothermal method with co-template triethylamine and tetraethylammonium bromide as crystal seeds, and then the layered SAPO-34 molecular sieves with different thicknesses were synthesized via changing the template composition. The prepared samples were characterized by X-ray diffraction, scanning electronic microscopy and NH3-temperature programmed desorption. The methanol to olefins catalytic performance of the SAPO-34 was evaluated by a fixed-bed reactor. The results show that the crystallization time of SAPO-34 shortens by to 36 h and the SAPO-34 cannot be produced without template. The template has an influence on the thickness of layered SAPO-34. The lamellar SAPO-34 has better light olefins selectivity than the flake and cubic ones, but its catalytic stability is slightly inferior to that of the flake one.
