摘要
以铜、镍为主要活性组分 ,通过添加一些金属 (如La、Ce、Co、Mn、Cr)制成三元催化剂 ,比较了它们的活性和选择性 ,发现以Cr为助剂三元金属催化剂性能较好 ,其最佳金属配比是 2∶3∶0
Basing copper(Cu) and nickel(Ni) on the component of activation,five different metal elements(La、Ce、Co、Mn、Cr)were chose,tri metal heterogeneous catalyst in hydrogenation of oils and fats was made,their activation and selectivity were compared and studied. We have found that chromium(Cr) was excellent and that optimum proportion of three metals(Cu、Ni、Cr)was 2∶3∶0 1
