Three different aluminum salts were used in the hydrothermal synthesis of boehmite. The salts employed were sulfate, chloride and nitrate. The prepared boehmites were calcined to obtain γ-Al₂O₃, then these supports were used to prepare NiMo/γ-Al₂O₃ catalysts and their activity was measured in the hydrotreating of Maya crude oil. The results showed that various key properties related to hydrotreating capability can be modified by using different precursor salts in the hydrothermal synthesis route of Al₂O₃ support. In this sense, in addition to pore diameter, the acidity of the alumina support plays an important role. To assess the acidity of each catalyst, additional reaction tests of the hydrocracking of cumene in a microreactor were performed. The catalysts were characterized by N₂ physisorption, XRD, FT-IR, SEM, HRTEM, and TPR.

在勃姆石的水热合成中使用了三种不同的铝盐。所使用的盐是硫酸盐，氯化物和硝酸盐。将制得的勃姆石煅烧，得到的γ-Al ₂ ø ₃，然后这些载体被用于制备的NiMo /γ-Al系_2种ö ₃催化剂和它们的活性在玛雅原油的加氢处理来测量。结果表明，在Al ₂ O ₃的水热合成路线中，通过使用不同的前体盐可以改变与加氢处理能力有关的各种关键性能。支持。从这个意义上讲，除了孔径之外，氧化铝载体的酸度也起着重要的作用。为了评估每种催化剂的酸度，进行了在微反应器中异丙苯加氢裂化的其他反应测试。通过N ₂物理吸附，XRD，FT-IR，SEM，HRTEM和TPR对催化剂进行了表征。
