Superfine -powder nickel was prepared through the following process： in 60℃ thermostatic water bath adding glycol, and under alkalescence condition Ni2^＋ was deoxidized by N2H4 ： H2O, finally through the procedures of water - laundering, centrifuging and drying. The superfine - powder product was put into a high pressure reactor as a catalyst to investigate the influence of the reacting conditions including pressure, temperature, reaction time, and catalyst/raw - material ratio, on the hydrogenation performance of unsaturated fatty acids.
