负载型Mo和Co-Mo催化剂由于工业上的广泛应用,多年来一直是催化工作者的重要研究课题.工业上应用的Mo和Co-Mo催化剂多以活性Al_2O_3和SiO_2-Al_2O_3为载体,近年来也有用TiO_2,ZrO_2和活性碳作为催化剂载体的研究报导.有关催化剂活性组分与载体之间相互作用对催化剂表面相结构和催化性能的影响方面研究已引起人们的重视。我们多年来在金属-载体相互作用研究基础上,以石油加氢精制催化剂为应用背景,开 Due to the widespread industrial application, supported Mo and Co-Mo catalysts have been an important research topic for catalytic workers for many years.Mo and Co-Mo catalysts used in industry are mostly supported by active Al 2 O 3 and SiO 2 -Al 2 O 3, and in recent years There are also reports on the use of TiO 2, ZrO 2 and activated carbon as catalyst carriers.Research on the influence of the interaction between the active components of the catalyst and the support on the phase structure and catalytic performance of the catalyst surface has drawn great attention. Over the years, based on the metal-support interaction study, we have used petroleum hydrotreating catalysts as the application background,
