In the present study, SAPO-34 particles were synthesized using hydrothermal (HT) and dry gel (DG) conversion methods in the presence of diethyl amine (DEA) as an organic structure directing agent (SDA). Carbon nanotubes (CNT) were used as a hard template in the synthesis procedure to introduce transport pores into the structures of the synthesized samples. The synthesized samples were characterized with different methods to reveal the effects of synthesis method and using hard template on their structure and catalytic performance in methanol to olefin reaction (MTO). DG conversion method results in smaller particle size in comparison with hydrothermal method, resulting in enhancing catalytic performance. On the other side, using CNT in the synthesis procedure with DG method results in more reduction in particle size and formation of hierarchical structure, which drastically improves catalytic performance.

在本研究中，在二乙胺 (DEA) 作为有机结构导向剂 (SDA) 存在下，使用水热 (HT) 和干凝胶 (DG) 转化方法合成 SAPO-34 颗粒。碳纳米管 (CNT) 在合成过程中用作硬模板，以将传输孔引入合成样品的结构中。合成的样品用不同的方法表征，以揭示合成方法和使用硬模板对其结构和甲醇制烯烃反应 (MTO) 催化性能的影响。与水热法相比，DG 转化法的粒径更小，从而提高了催化性能。另一方面，
