【 摘 要 】

A new thermodynamic parameter is defined as a descriptor of the energy of the metal-sulfide bond. This parameter enables a linearcorrelation with the natural logarithm of the HDS activity. Thelinear correlation obtained reaffirms that those descriptors that account properly for the energy of metal-sulfur bond will tend to generate higher quality linear correlations with the catalytic activity. This result supports those kinetic models where the decisive step in the HDS process is associated with the rupture of metal-sulfur bond. This study raises the conjecture of the possible existence of transient active phases responsible for the catalysis of HDS process.
