摘　　要：浆态床渣油加氢技术的核心和关键是采用了高分散性催化剂,其具有定向催化加氢活性和抑制结焦能力,保证了渣油中沥青质的高效轻质化,维持装置长周期稳定运行。而在分散型催化剂中添加助金属,不仅可以有效降低催化剂的成本,还可以显著提高催化剂的加氢活性。本文全面综述了浆态床渣油加氢裂化技术中分散型双金属催化剂的研究进展,包括钴-钼、镍-钼、铁-镍等双金属催化剂,重点介绍了双金属催化剂的活性和活性相结构,同时分析总结了不同双金属催化剂的优缺点。通过探索双金属催化中金属之间的协同作用,深入认识催化剂活性相结构,展望分散型双金属催化剂的未来发展,对渣油高效转化催化剂的开发具有重要意义。To ensure efficient conversion of asphaltenes in residual oil to light fractions under long-term stable operation, it is crucial to use highly-dispersed catalysts that have the activity of oriented catalytic hydrogenation and the ability to restrain coke formation in slurry-phase hydrocracking. Bimetallic dispersed catalyst fabricated by adding promoter metals could effectively reduce the cost and significantly improve the hydrogenation activity. In this paper, the research progress of dispersed bimetallic catalysts in slurry-phase hydrocracking technology are comprehensively reviewed, including the cobalt-molybdenum,nickel-molybdenum, iron-nickel and other bimetallic catalysts, with emphasis on their activities and active phase structures, and the pros and cons of different bimetallic catalysts are analyzed and summarized. As for the future research on dispersed bimetallic catalysts, it is of great significance for the development of high-efficiency catalysts for residual oil by exploring the synergy between metals and the structure of the active phase of the catalysts.
