One of the reasons for the gigantic interest in SAPO-34 by researchers is to commercialize SAPO-34 effectively by considering the economic, energy, and activity aspects as it has found enormous uses in various industrial applications. The present study focuses on the preparation method named the dry gel conversion method for synthesizing SAPO-34. Four different structure-directing agents (SDA’s) (tetraethylammonium hydroxide (TEAOH), triethylamine (TEA), morpholine, diethylamine (DEA)) in different amounts are utilized for the synthesis of SAPO-34 along with alumina, silica, phosphorus precursors. Two sets of a mixed combination of the templates are taken into consideration for SAPO-34, which are TEAOH/TEA/Morpholine/DEA with the molar composition of 0.2/0.4/0.6/0.8 and 0.4/0.2/0.8/0.6, and crystallization time is taken as 3, 5, and 8 h. XRD, FTIR, TPD, nitrogen adsorption, TGA, SEM, EDX, TEM investigated the catalyst’s physicochemical properties. For both gel compositions, the pure phase of SAPO-34 is formed at 5 h, with the variation in the intensity of crystallinity. The micropore surface area and external surface area of the prepared catalysts fall in the range of 79–697 m²/g and 44–175 m²/g, respectively.

研究人员对 SAPO-34 产生巨大兴趣的原因之一是通过考虑经济、能源和活动方面来有效地将 SAPO-34 商业化，因为它在各种工业应用中都有巨大的用途。本研究的重点是用于合成 SAPO-34 的称为干凝胶转化法的制备方法。四种不同的结构导向剂 (SDA)（氢氧化四乙铵 (TEAOH)、三乙胺 (TEA)、吗啉、二乙胺 (DEA)）以不同的量用于合成 SAPO-34 以及氧化铝、二氧化硅、磷前体。SAPO-34考虑了两组模板的混合组合，即摩尔组成为0.2/0.4/0.6/0.8和0.4/0.2/0.8/0.6的TEAOH/TEA/吗啉/DEA，以及结晶时间分别为 3、5 和 8 小时。XRD、FTIR、TPD、氮吸附、TGA、SEM、EDX、TEM研究了催化剂的理化性质。对于两种凝胶组合物，SAPO-34 的纯相在 5 小时后形成，结晶度强度有所变化。所制备催化剂的微孔表面积和外表面积在79-697 m范围内^{分别为 2} /g 和 44–175 m ² /g。
