摘要
采用Pd/C做催化剂,在CO2超临界状态下对一级大豆油进行氢化反应研究,拟用来作润滑油基础油,确定了最佳工艺条件:催化剂用量0.06%,反应时间45min,温度50℃,总压力9MPa,搅拌速度200r/min。在此条件下,所得氢化大豆油的碘值为84.77gI2/100g;黏度为7.85Pa.s;过氧化值为0.83mmol/kg;酸值为0.15mgKOH/g。产品可代替3%传统的矿物油基础油,是一种无污染,可再生,绿色环保的新能源。
With Pd/C used as a catalyst,the hydrogenation process of the best soybean oil was conducted in the supercritical CO2 condition and it was used as basic lubricating oil.Then,the optimum conditions were determined as follows：the amount of catalyst 0.06%,reaction time 45 min,the reaction temperature 50 ℃,total pressure 9 MPa and stirring speed 200 r/min.Under the said condition,it was obtained for the Hydrogenation of soybean oil that：the iodine value was 84.77 gI2/100 g;the viscosity value was 7.85 Pa·s;POV was 0.83 mmol/kg;AV was 0.15 mg KOH/g.The product could be used to replace 3% of the traditional mineral base oil,so that a new clean,renewable and green energy was found out.
