最近几年,对过渡金属硫化物的化学性质,其结构及其加氢脱硫(HDS)活性,以及它们之间的相互关系有了更深一层认识,对工业实用的催化剂体系,随着Co-Mo-S结构模型的提出与证实,也逐渐弄清了其活性相和作用机理。Chevrel化合物的研究结果则开辟了一个新领域。本文对HDS催化剂的研究动态作了评述,试图借以说明理论与技术相互作用与促进发展的关系。本文还介绍了利用MES和EXAFS等新技术研究HDS催化剂的成果。
In recent years, there has been a deeper understanding of the chemical properties of transition metal sulfides, their structure and their HDS activity, and their interrelationships. For practical industrial catalyst systems, as the Co- Mo-S structural model proposed and confirmed, but also gradually clarify the active phase and mechanism of action. The research results of Chevrel compounds open up a new area. This paper reviews the research progress of HDS catalysts in an attempt to illustrate the relationship between theory and technology and the promotion of development. This article also describes the use of MES and EXAFS and other new technologies HDS catalyst research results.
