Abstract:

Hydrodesulfurization (HDS) catalyst is an indispensable part of hydrodesulfurization technology. Especially, as a typical hydrodesulfurization catalyst, the alumina supported metal sulfide catalyst is widely used in the industrial production. In this paper, the research progress of alumina supported metal sulfide catalyst, including the active phase model of the catalysts and the effects of various additives on the structure-activity relationship of hydrodesulfurization catalysts, is systematically reviewed. Thereinto, the research progress of active phase models, including 5 classical models, and their differences and correlations are emphatically discussed. Meanwhile, the effects of various additives (transition metals and main group elements including ⅠA, ⅡA, ⅢA, etc.) on the structure-activity relationship of hydrodesulfurization catalysts are discussed. Finally, the future development direction of hydrodesulfurization catalysts is prospected. Understanding the structure and morphology of the active phase and the complex catalytic mechanism of the catalyst on the atomic scale, creating controllably highly active and selective multi-functional catalysts with adjustable properties basing on the deep understanding of the catalytic mechanism and the active phase are important directions for hydrodesulfurization catalysts in the future.

Key words: hydrodesulfurization, catalyst, alumina, active phase, additives
