摘　　要：采用Pd/C作催化剂,以碘值为考察指标,在超临界CO2状态下对三级大豆油进行氢化制备润滑油基础油,确定最佳工艺条件为:催化剂用量0.06%,反应时间45 min,反应温度50℃,CO2压力5.5 MPa、加入氢气至总压力9 MPa,搅拌速度200 r/min。在此条件下,所得氢化大豆油的碘值(I)为88.20 g/100 g,黏度为9.89 Pa.s,过氧化值为5.6 mmol/kg,酸值(KOH)为0.68 mg/g。Pd/C was used as a catalyst, and the hydrogenation process of the national grade Ⅲ of soybean oil was conducted in the supercritical CO2 condition to obtain lubricant base oil. The optimum conditions were determined as follows： the amount of catalyst 0.06%, reaction time 45 min, reaction temperature 50 ℃, pressure of CO2 5.5 MPa, total pressure 9 MPa, and stirring speed 200 r/min. Under the optimum conditions, the indexes of the hydrogenated soybean oil were：iodine value 88.20 gI/100 g, viscosity value 9.89 Pa · s,POV 5.6 mmol/kg, AV 0.68 mgKOH/g.
