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 C6 solvent oil.%研究了C6溶剂油加氢脱硫脱芳工艺.加氢精制段采用MC-1为催化剂,吸附脱硫段采用HTZM-1为脱硫剂,反应条件:温度260℃、空速6h-1、压力2.0 MPa、氢油体积比100.结果表明:产品中的硫质量分数小于0.5 μg/g;加氢脱芳段采用HTB-1H为加氢催化剂,反应条件:温度120℃、空速0.5h-1、压力0.6 MPa、氢油体积比100.结果表明:产品中芳烃质量分数小于100 μg/g,满足了新的C6溶剂油标准.
