Aim and Objective: The research focuses on recent progress in the production of light olefins. Hence, as the common catalyst of the reaction (SAPO-34) deactivates quickly because of coke formation, we reorganized the mechanism combining SAPO-34 with a natural zeolite in order to delay the deactivation time.

Materials and Methods: The synthesis of nanocomposite catalyst was conducted hydrothermally using experimental design. Firstly, Clinoptilolite was modified using nitric acid in order to achieve nano-scaled material. Then, the initial gel of the SAPO-34 was prepared using DEA, aluminum isopropoxide, phosphoric acid and TEOS as the organic template, sources of Aluminum, Phosphor, and Silicate, respectively. Finally, the modified zeolite was combined with SAPO-34's gel.

Results: 20 different catalysts due to D-Optimal design were synthesized and the nanocomposite with 50 weight percent of SAPO-34, 4 hours Crystallization and early Clinoptilolite precipitation showed the highest relative crystallinity, partly high BET surface area and hierarchical structure.

Conclusion: Different analyses illustrated the existence of both components. The most important property alteration of nanocomposite was the increment of pore mean diameters and reduction in pore volumes in comparison with free SAPO-34. Due to the low price of Clinoptilolite, the new catalyst renders the process as economical. Using this composite, according to the formation of multi-sized pores located hierarchically on the surface of the catalyst and increased surface area, significant amounts of Ethylene and Propylene, in comparison with free SAPO-34, were produced, as well as the deactivation time was improved.

目的与目的：研究轻质烯烃生产的最新进展。因此，由于反应的常用催化剂（SAPO-34）由于焦炭的形成而迅速失活，我们重新组织了将 SAPO-34 与天然沸石结合的机制，以延迟失活时间。

材料与方法：纳米复合催化剂的合成采用实验设计进行水热。首先，使用硝酸对斜发沸石进行改性以获得纳米级材料。然后，使用 DEA、异丙醇铝、磷酸和 TEOS 作为有机模板，分别使用铝、磷和硅酸盐的来源制备 SAPO-34 的初始凝胶。最后，将改性沸石与 SAPO-34 的凝胶结合。

结果：由于 D-Optimal 设计合成了 20 种不同的催化剂，具有 50 重量％的 SAPO-34、4 小时结晶和早期斜发沸石沉淀的纳米复合材料显示出最高的相对结晶度、部分高 BET 表面积和分级结构。

结论：不同的分析说明了这两种成分的存在。与游离 SAPO-34 相比，纳米复合材料最重要的性能变化是孔平均直径的增加和孔体积的减少。由于斜发沸石的价格低廉，新催化剂使该工艺变得经济。使用这种复合材料，根据催化剂表面分级的多尺寸孔的形成和增加的表面积，与游离的 SAPO-34 相比，产生了大量的乙烯和丙烯，以及失活时间得到改善。
