To solve the challenges of diffusion of large molecules of oil into the SAPO-34 pores, secondary carbon and polymeric templates are used in sonohydrothermal synthesis method. Structure of the catalysts was estimated by BET, XRD, TPD, EDX, FESEM, HRTEM, and FTIR analyses. The best pore distribution was obtained for the catalyst synthesized by charcoal active, in which the conversion was 83% for the esterification reaction of oleic acid. To increase the activity of this catalyst, 5% CeO₂ was accommodated on it by sono-solvothermal method which resulted in 94% conversion. Kinetic studies showed that for all synthesized catalysts, the degree of esterification reaction was of the first order and CeO₂ loaded sample had the highest rate constant, equal to 0.0013 min^-1. By increasing the pore radius and acidic strength of the catalyst, the reaction rate constant increases due to the overcoming the penetration of large oil molecules and increased acidic activity.

为了解决大分子油扩散到SAPO-34孔中的难题，在声水热合成方法中使用了次级碳和聚合物模板。通过BET，XRD，TPD，EDX，FESEM，HRTEM和FTIR分析估算催化剂的结构。通过活性炭合成的催化剂获得了最佳的孔分布，其中油酸的酯化反应转化率为83％。为了提高该催化剂的活性，通过声波溶剂热法将5％的CeO ₂容纳在其上，导致94％的转化率。动力学研究表明，对于所有合成的催化剂，酯化反应的程度均为一级，负载CeO _2的样品的速率常数最高，等于0.0013 min ^-1。通过增加催化剂的孔半径和酸性强度，由于克服了大油分子的渗透和增加的酸性活性，反应速率常数增加了。
