he hydrogen desulfurization of four kinds of low-quality diesel oils using HPL-1 as was studied on a smallsized hydrogenation unit. The reaction kinetics and the effects of reaction temperature, reaction pressure, volume space velocity and volumetric hydrogen/oil ratio on desulfurization rate have been investigated. The results showed the optimal hydrodesulfurization condition as follows: reaction temperature 360 ℃, pressure 7.0 MPa, space velocity 1.0h-1, and volumetric hydrogen/oil ratio 800:1. Under this condition, the lowquality diesel desulfurization rate can be reached up to 9657%. Moreover, a 0.5 order kinetic model for lowquality diesel was setabilished based on the factors of pressure, hydrogen/oil ratio and space velocity parameters correction. The results indicate that the experimental values and simulation values are in good coincide for four kinds of low-quality diesel sulfur content.
