Hydrodesulfurization (HDS) technology is one of the most important and new goals of researchers in the petroleum refining industry for reduction of the sulfur content of gasoil to the lower limits. In this research, a systematic investigation was carried out to determine the kinetics of the HDS reaction for dibenzothiophene in gasoil. Experiments were carried out in a micro trickle bed reactor in a temperature range of 360-380C°, a pressure range of 55-70 bars and the LHSV of 0.5- 2 h-1. A power law model was considered for determination of the kinetic parameters of the HDS reaction, and the reaction rate order and activation energy of this model were calculated. The results revealed that the order of reaction is 1.4 and the activation energy was estimated to be 15 kcal/mol.
