Abstract: The hydrodesulfurization and dearomatization process for C6 solvent oil were investigated in multisteps including hydrorefining, adsorptive desulfurization and hydrodearomatization. The results show when the catalyst for hydrorefining section is MC-1 and for adsorption desulfurization section is HTZM-1, and reaction conditions are listed below: temperature 260 ℃, space velocity 6 h-1, pressure 2.0 MPa and the volume ratio of hydrogen to oil 100, the sulfur content of product can be reduced to 0.5 μg/g; Hydrodearomatization was carried out with HTB-1H as the catalyst under the following reaction conditions: temperature 120 ℃, space velocity 0.5 h-1, pressure 0.6 MPa and the volume ratio of hydrogen and oil is 100, the aromatic content of product is reduced to less than 100 μg/g to meet the new standard of C6 solvent oil.
