Abstract: Based on the reaction characteristics of hydrotreating process, the effect of process conditions on the hydro-saturation of aromatic hydrocarbon in VGO feed was investigated and a basic kinetic equation of aromatic hydrocarbon hydro-saturation was proposed. In order to extend the application of this equation, the effect of various VGO feeds on the activation energy of hydro-saturation reactions was studied and corresponding empirical correlations were obtained. Finally, a better kinetic model for hydro-saturation of aromatic hydrocarbon in VGO was set up, and the validated result showed that the calculated value agreed well with the test datum.
