油脂加氢催化剂Cu-Ni-Ru和进口催化性能比较的研究

Catalytic Properties Research of Cu-Ni-Ru Compare with the Imported Catalyst on Hydrogena tion Catalyst

文章在相同的氢化条件下,研究了进口催化剂9910、2021和Cu-Ni-Ru分别在160℃,180℃,200℃下的氢化性能。结果表明:三种催化剂在每一温度下对大豆油氢化的活性大小顺序为Cu-Ni-Ru>9910>2021;三种催化剂的碘值和折光指数都随温度的升高而增加。Cu-Ni-Ru、9910和2021三种催化剂均在三种温度下氢化时,C18:1(油酸)反式脂肪酸在160℃下含量最低,C18:2(亚油酸)反式脂肪酸在180℃下含量最低。说明低温有利于反式脂肪酸的降低;Cu-Ni-Ru、9910和2021在相同温度条件下氢化时,催化剂比Cu-Ni-Ru比9910和催化剂2021更能使反式脂肪酸酸含量降低,有更高的选择性。

In the same hydrogenation conditions, the paper researched the hydrogenation performance of the imported catalyst 9910, 2021 and Cu-Ni-Ru at 160 ℃, 180 ℃, 200 ℃. The results showed that： Three catalysts＇ order of activity on hydrogenated soybean oil in each temperature was Cu-Ni-Ru〉9910〉2021. Three catalyst＇s iodine value and refractive index increased with increasing temperature. When catalyst Cu-Ni-Ru, 9910 and 2021 were hydrogenated at three temperatures, C l 8： I （oleic acid） of trans fatty acids was the lowest at 160 ~C, C18：2 （linoleic acid） of trans-fatty acids was the lowest at 180 ~C. This showed that low temperature was conducive to the reduction of trans- fatty acids; When catalysts Cu-Ni-Ru, 99 1 0 and 2021 were hydrogenated at the same temperature conditions, more than 9910 and 2021 catalyst can reduce the acid content of trans fany acids, and have higher selectivity.
