【摘要】 建立了优化中国菜油氢化操作的方法。利用中国菜油氢化反应动力学模型,在工业生产普遍采用的条件范围内,选择氢化压力、催化剂用量等,以在最高菜油含硫量下获得所要求的产品。计算表明,在压力为2.94×10~5Pa(表压),催化剂用量为0.2kg(Ni)/100kg(油),氢化时间为190min条件下,要将中国菜油氢化至碘价低于80,则原料菜油中Rancy-Ni硫含量不可超过9ppm.所提供的方法能将任何非优操作转变为最优操作更多还原

【Abstract】 A method to optimize the hydrogenation operation of Chinese Rapeseed Oil is proposed. The kinetic model for hydrogenation of Chinese Rapeseed Oil was used to select values for hydrogen pressure, catalyst dosage, etc. So that a desired product (Iodine Value<80) could be obtained under the maximum content of sulfur compounds in the rapesed oil. The calculation results indicate that under the following conditions: pressure: 2.94×10~5Pa(G), dose of catalyst: 0.2% (Ni/oil(W)), time: 190min, the maximum content of sulfur compounds(Rancy—Ni sulfur) in Chinese Rapeseed Oil can’t be more than 9 ppm. The methodology is suggested whereby any nonoptimal operation can be changed to optimal operation.更多还原
