Journal ArticleDOI
Hydrodenitrogenation of Petroleum
Edward Furimsky,F.E. Massoth +1 more
TL;DR: In this article, it was shown that at least four different catalytic sites are required to interpret experimental observations in contrast with a dual site site concept, which only considered two sites.
Journal ArticleDOI
Elemental Composition Analysis of Processed and Unprocessed Diesel Fuel by Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
TL;DR: In this paper, electrospray ionization was found to ionize selectively basic pyridine homologues, responsible for deactivation of hydrotreatment catalysts and instability of fuels during storage.
Journal ArticleDOI
Hydrogen activation by transition metal sulfides
TL;DR: In this paper, the authors show that for the supported catalysts, the amount of adsorbed hydrogen per unit of Mo(W) is significantly greater than for the non-supported catalysts.
Journal ArticleDOI
Synthesis and Activity of a New Catalyst for Hydroprocessing: Tungsten Phosphide
Paul Clark,Wei Li,S. Ted Oyama +2 more
TL;DR: A tungsten phosphide, WP, hydrotreating catalyst was prepared by temperature-programmed reduction of an X-ray amorphous Tungsten phosphate at a heating rate of 0.0167 K s−1 and a 2-h soak at the final temperature of 938 K.
Journal ArticleDOI
Resolution of 10 000 Compositionally Distinct Components in Polar Coal Extracts by Negative-Ion Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
TL;DR: In this paper, electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) was applied to the analysis of Illinois No. 6 and Pocahontas No. 3 pyridine coal extracts.

Reactivities, reaction networks, and kinetics in high-pressure catalytic hydroprocessing
Michael J. Girgis,Bruce C. Gates +1 more
TL;DR: A critical review of the literature of catalytic hydroprocessing reactions can be found in this article, where the authors present thermodynamic, reactivity, reaction network and kinetic data of hydrogenation of aromatic hydrocarbons, hydrodesulfurization, hydrodenitrogenation and hydrodeoxygenation.

Structure-Function Relations in Molybdenum Sulfide Catalysts: The "Rim-Edge" Model
M. Daage,R.R. Chianelli +1 more
TL;DR: In this paper, the average stacking heights of poorly crystalline MoS2 powders are estimated by X-ray crystallography and for the first time correlated with the selectivity of the catalyst for hydrogenation versus HDS (hydrodesulfurization).
Journal ArticleDOI
Structure and Function of the Catalyst and the Promoter in Co—Mo Hydrodesulfurization Catalysts
TL;DR: The authors discuss le role d'un promoteur modifiant un catalyseur, notamment determination du nombre de sites actifs, and discuss the role of un promoteur in modifying a catalyseure.

In situ Mössbauer emission spectroscopy studies of unsupported and supported sulfided CoMo hydrodesulfurization catalysts: Evidence for and nature of a CoMoS phase
TL;DR: In this paper, the structure and type of phases present in sulfided alumina-supported, as well as unsupported, Co-Mo catalysts is obtained from in situ Mossbauer emission spectroscopy (MES) studies.
Journal ArticleDOI
Characterization of the structures and active sites in sulfided CoMoAl2O3 and NiMoAl2O3 catalysts by NO chemisorption
Nan-Yu Topsøe,Henrik Topsøe +1 more
TL;DR: In this paper, infrared and volumetric studies of NO adsorption have been used to elucidate the type of surface structures present in sulfided Co Al 2 O 3, Ni Al 2O 3, Mo Al 2 o 3, CoMo S 2, and Ni Al O 3 catalysts.
