Lumping Kinetics of Hydrodesulfurization for Crude Longkou Shale Oil

Abstract:

New lumping kinetic models, considering the effects of the nitrogen content in product and the correction coefficient of LHSV, were proposed to describe the hydrodesulfurization of crude Longkou shale oil. The kinetic parameters were obtained using nonlinear regression of the experimental data which were conducted in a bench-scale trick-bed reactor with NiW/Al₂O₃ catalyst at various conditions. The results show that the 4-lump model is the optimal model. The values of apparent activation energies of lumps 1, 2, 3 and 4 are 51.14, 62.64, 130 and 166.42kJ/mol, respectively. The validation and application of the 4-lump model were also investigated.
