负载型贵金属钯-氧化铝催化剂用于大豆油选择氢化

Selecting Hydrogenation of Soybean Oil by Catalyst Pd/Al_2O_3

通过对大豆油的选择氢化实验 ,就各反应条件如温度、反应时间、催化剂负载量对贵金属催化剂的选择氢化催化活性的影响及催化剂回收利用进行了考察 ,初步确定适合工业化大豆油选择氢化的工艺条件 ,并对如何降低氢化过程中生成的反式烯酸做了初步的探讨。

Soybean oil was hydrogenated by Pd/Al 2O 3,various factors in soybean oil industry hydrogenation were investigated,such as temperature,reaction time,the amount of Pd impregnated on Al 2O 3 and recycle of catalyst.Trans isomer in hydrogenated fat was reduced by lowering hydrogenation temperature.
