In this work, the influence of reaction conditions on hydrocarbon distribution and product quality was tested to obtain the rule of variation with different residence time. A semi-experience and semi-mechanism dynamics model was established and modified. Based on the simulation results, the hydrogenation reactor is divided into five regions: the upper two regions are mainly saturated with most of tri-cyclic and bi-cyclic aromatics, and 90％ of nitrides are converted, while all simple sulfide and some 4,6-DMDBT compounds undergo transformation reactions. In the lower three regions, the reaction rate of HDS and HDN slows down, while the rate of monocyclic aromatic saturation increases. The HDS, HDN and HDA rates of the optimized catalyst grading scheme are significantly increased.
