大豆油加氢高活性催化剂的研究

Study on High Active Catalyst for Hydrogenation of Soybean Oils

采用并流沉淀法制备了Cu－Ni二元催化剂，研究了SiO2的加入量和焙烧温度对催化剂活性的影响。结果表明加入SiO2可明显提高Cu－Ni二元催化剂活性，加入量以Cu(Ni):SiO2=1.5为好，最佳焙烧温度300℃。文中方法制备的催化剂用于大豆油的催化加氢，表现出很高的催化活性。

Abstract:Cu- Ni bibasic catalyst is prepared by paralled flow precipitation method using silica as disperser. The amount of silica addition and calcination temperature are studied. The result indicates that activity of Cu -Ni bibasic catalyst can be raised significantly by adding Si02. The suitable amount of Si02 is Cu(Ni)/Si02 = 1.5,optimized calcination temperature is 300. The catalyst prepared by mentioned method is of high activity for hydrogenation of soybean oils.
