摘要
Abstract
The hydrodesulfurization(HDS) of diesel over Ni-Mo/TiO2-Al2O3 catalyst in a high pressure trickle-bed reactor was studied. The kinetics experiments for the HDS were carried out under the conditions of reaction temperature of 280-360 ℃ , hydrogen pressure of 5-7 Mpa, hydrogen/oil volume ratio of 300-900 and LHSV of 1-6 h-1. The kinetics model for the HDS was established. The experimental data were fitted by Levenberg-Marquard method. The result indicates that the HDS over the Ni-Mo/TiO2-Al2O3 catalyst is a 1.5 order reaction and its apparent activation energy is 78 002 J/ mol. The calculated values are in good agreement with the experimental results and the average relative deviation is 2.7%.关键词
