Abstract	Researchers synthesized the silicoaluminophosphate (SAPO) particles based on dry gel conversion method using diethyl amine (DEA) as an organic structure directing agent (SDA). They introduced transport pores into the crystalline structure of the catalyst using carbon nanotubes (CNT) as a hard template. They examined the significance of molar ratio of CNT in the starting gel and the other synthesis parameters such as crystallization time, gel drying temperature and water content added in the crystallization stage, on crystallinity of SAPO-34, crystal phase, particle size and morphology. Fischer test results showed that, all the parameters have significant effect on the crystallinity of the synthesized samples.
