TL;DR: In this article, the effect of Co or Ni on the HDS activity of Mo/alumina was studied by using dibenzothiophene (DBT) and 4,6-dimethyldibenzethiophene(46DMDBT), and the reaction was carried out at 340°C under a 4 MPa total pressure.

TL;DR: In this article, the authors carried out ab initio calculations using density functional theory under the generalized gradient approximation for periodic systems and found that the edge substitution model emerges as the most stable structure and provides an excellent agreement with local structures experimentally determined on real catalysts by extended X-ray absorption fine structure.

TL;DR: In this article, the electronic foundations of the Sabatier principle as applied to HDS catalysis are presented with a special attention to the electronic foundation for HDS catalysts.

TL;DR: In this paper, the metal-sulfur bond strength was defined as the cohesive energy per metal sulfur bond and all experimental HDS activities fit nicely on a single volcano master curve when plotted against this simple energetic parameter.

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.
