What are the roles of Mo, Ni, and Co in hydrogenation catalysts? Or rather, what are their main functions? What are the differences between Pt, Pd, and non-precious metals?
The Ni(Co)Mo(W)/Al2O3 catalyst is the most commonly used hydrogenation catalyst in industry. Phosphorus is a frequently employed additive in Ni(Co)Mo(W)/Al2O3 hydrogenation catalysts, used to improve the physicochemical properties of these catalysts. This article discusses the effects of phosphorus on the pore structure, acidity, and dispersion of active components of Ni(Co)Mo(W)/Al2O3 hydrogenation catalysts, as well as its impact on the catalytic performance for hydrodesulfurization (HDS) and hydrodenitration (HDN)
Dear marine friends, I would like to ask: which component has high desulfurization activity, and which one has high denitrification activity? What are the differences among these components, and what are their advantages and disadvantages?
