Co-PMo catalysts were prepared from the 12-molybdophosphoric heteropolyacid and cobalt citrate on the base of freshly-synthesized alumina and mixed MCM-41-Al₂O₃ material. Carriers and catalysts were characterized by the following techniques: X-ray powder diffraction, low-temperature N₂ adsorption, NH₃-TPD, Raman spectroscopy, X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy. Prepared catalysts were tested in hydrodesulfurization of dibenzothiophene and hydrogenation of naphthalene. It has been shown that mesoporous silica incorporation into alumina can improve morphological properties of the CoMoS active phase as well as the overall HDT activity.

Co-PMo 催化剂由 12-磷酸钼杂多酸和柠檬酸钴在新合成的氧化铝和混合 MCM-41-Al ₂ O ₃材料的基础上制备。载体和催化剂通过以下技术表征：X 射线粉末衍射、低温 N ₂吸附、NH ₃ -TPD、拉曼光谱、X 射线光电子能谱和高分辨率透射电子显微镜。制备的催化剂用于二苯并噻吩加氢脱硫和萘加氢试验。已经表明，将介孔二氧化硅掺入氧化铝可以改善 CoMoS 活性相的形态特性以及整体 HDT 活性。
