摘要/Abstract

摘要： 首先制备Na-ZSM-5载体，再将金属Ru通过浸渍法负载于载体上，获得负载型金属催化剂。然后用电化学催化法对催化剂活化，将活化后的催化剂应用于玉米油异构化反应中，研究反应条件对玉米油异构化的效果，结果发现催化剂添加量5%、异构化时间3 h、搅拌速率600 r/min、异构化温度160 ℃为最佳反应条件，并且负载型Ru/Na-ZSM-5催化剂经反复使用5 次后，催化剂相对活性依然保持在75.2%。最后对反应后玉米油的主要成分与理化特性进行研究，发现得到的富含共轭亚油酸（conjugated linoleic acid，CLA）的玉米油中c9,t11-CLA相对含量为12.32%，t10,c12-CLA相对含量为8.45%，而反式油酸相对含量仅为1.63%。在理化特性方面，其酸值为1.17 mg/g，碘值为103.08 g/100 g，过氧化值为4.31 mmol/kg，皂化值为201.56 mg/g，不皂化物含量为16.53 g/kg，具有较好的品质。

Abstract: Na-ZSM-5 support was prepared and loaded with Ru by an impregnation method to obtain a supported metal catalyst. The catalyst was activated by electrochemical catalysis for application in the isomerization of corn oil. The influence of the reaction conditions on the isomerization efficiency was studied. The optimum reaction conditions were determined as follows: catalyst dosage 5%, isomerization time 3 h, stirring speed 600 r/min, and isomerization temperature 160 ℃. The relative activity of the supported Ru/Na-ZSM-5 catalyst was maintained at 75.2% after repeated use for five times. Finally, the major components and physicochemical properties of the reacted corn oil were studied. The results showed that the oil contained 12.32% c9,t11-CLA and 8.45% t10,c12-CLA as well as only 1.63% trans oleic acid. Its acid value was 1.17 mg/g, iodine value 103.08 g/100 g, peroxide value 4.31 mmol/kg, saponification value 201.56 mg/g, and unsaponifiable matter content 16.53 g/kg, which revealed good quality.
