Intrinsic Thiophene Hydrodesulfurization Kinetics of a Sulfided NiMo/SiO2Model Catalyst: Volcano-Type Behavior

Autor: Emiel J. M. Hensen, J.W. Niemantsverdriet, L. Coulier, J.A.R. van Veen, Armando Borgna, J.C. Schouten, M.H.J.M. de Croon

Publikováno v: Catalysis Letters, 90(3-4), 117-122. Springer

A realistic planar model of a silica-supported NiMo sulfide hydrotreating catalyst (i.e., a planar SiO2 single crystal spincoated with active metal oxides) was used to study the intrinsic kinetics of thiophene hydrodesulfurization over a broad temp.

The combination of thiophene hydrodesulfurization (HDS) activity measurements and X-ray photoelectron spectroscopy on flat model systems of sulfided HDS Mo catalysts showed that sulfided Ti-species can act as a promoter in the same way as Co and Ni,

Influence of support-interaction on the sulfidation behavior and hydrodesulfurization activity of Al2O3-supported W, CoW, and NiW model catalysts

Publikováno v: Journal of Physical Chemistry B, 106(23), 5897-5906. American Chemical Society

The interaction of Co (or Ni) and W with the Al2O3-support influences the sulfidation behavior and thiophene hydrodesulfurization (HDS) activity of COW and NiW model catalysts. High calcination temperatures retard the sulfidation of Co, Ni, and W to

Surface science models for CoMo hydrodesulfurization catalysts: Influence of the support on hydrodesulfurization activity

Autor: J.W. Niemantsverdriet, J.A.R. van Veen, Gurram Kishan, L. Coulier

Publikováno v: Journal of Vacuum Science and Technology A: Vacuum, Surfaces, and Films, 19(4), 1510-1515. AVS Science and Technology Society

Flat model systems of supported oxidic COMO hydrodesulfurization (HDS) catalysts, consisting of a conducting substrate with a thin SiO2 or Al2O3 layer on top of which the active catalytic phase is deposited by spin coating, were used to study the inf

Correlation between hydrodesulfurization activity and order of Ni and Mo sulfidation in planar silica-supported NiMo catalysts: the influence of chelating agents

Autor: J.A.R. van Veen, V.H.J. de Beer, L. Coulier, J.W. Niemantsverdriet

Publikováno v: Journal of Catalysis, 197(1), 26-33. Academic Press Inc.

Surface science models of silica-supported NiMo catalysts have been prepared to study the formation of the active phase (“NiMoS”) in hydrotreating catalysts. Combination of XPS and thiophene hydrodesulfurization (HDS) measurements shows that the

Publikováno v: Journal of Catalysis, 196(1), 180-189. Academic Press Inc.

Silica-supported NiWS catalysts with a high activity for thiophene hydrodesulfurization are obtained when chelating agents such as 1,2-cyclohexanediamine-N,N,N',N'-tetraacetic acid (CyDTA), ethylenediaminetetraacetic acid, or nitrilotriacetic acid ar
