При использовании одного и того же коли-Ю чества Ni--К-А1 катализатора прогидрировали 9 раз по 100 г жирных кислот, в то же врем в этих же услови х после шестикраткого использовани известный Ni-Ti-Al катализатор практически тер ет свою первоначальную активность. Были исследованы гидрогенизаты, полученные на основе Ni-Ti-Al и Ni-К-Al катализаторов , на содержание кислот мзо-строеТаблица 2When using the same amount of Ni — K-A1 catalyst, it was hydrated 9 times in 100 g of fatty acids, while under the same conditions, after six times of use, the known Ni-Ti-Al catalyst practically lost its original activity. The hydrogenates obtained on the basis of Ni – Ti – Al and Ni – K – Al catalysts were investigated for the content of Mzo – stroy acids. Table 2

Claims

1. A catalyst for the hydrogenation of fatty acids, which is leached. The results of the experiments showed that the content of trans-xlots increases with increasing frequency of use of the same amount of catalyst.

It should be noted that the hydrogenate obtained on the proposed catalyst contains significantly less granic acids than the hydrogenate obtained on the Ni-Ti-Al catalyst (see Table 2).

To determine the optimal amount of potassium supplement introduced into the nickel-aluminum alloy, catalysts with a potassium content of 1 were tested; 1.5; 2; 2.5; 3 wt. % in the hydrogenation of fatty acids. The results of the experiments are given in table. 3
