In order to raise hydrogenant efficiency, in this experiment, the hydrogen addition treatment was carried out with a nickel-based catalyst at a lower temperature and under a lower pressure, and the better absorptive auxiliary was used. The characteristics of this technology are obtained in the the lower temperature, lower pressure, less time and more perfect. Results showed that the optimum technology condition was as followes: the reaction time of 100～110?min,reaction temperature of 100?℃, catalyst dosage of 0.55?kg,reaction pressure of 0.55?Mpa. In this reactive condition, the lard can be hydrogenated and hydrogenated oil can be obtained. The treated oil may be applied to produce stearic acid which melting point is 56～58?℃ and iodine value≤2. About 15?min of the reaction time can be saved, and 0.05?Mpa of the average pressure can be reduced, if the auxiliary is added, which demonstrated taht this kind of auxiliary has better improved effects.
