中文摘要：
一系列 Ni 与不同支持基于催化剂，基本添加剂被顺序的受精方法准备。催化剂被 XRD，赌注， H2-TPR 和 CO2-TPD 技术描绘。基本添加剂的介绍提高了 catalyats 的盐基度并且由在 Ni 2+ 和基本添加剂之间的强壮的相互作用支持了 Ni 粒子的 dispersities，这被发现。在 Ni 之中基于催化剂， 10%Ni/10%La2O3 /ZrO2 在山梨糖醇 hydrogenolysis 显示出优异表演。Ni 和 La2O3 的 synergistic 效果被证明在选择合成起一个必要作用例如并且 1,2-PG。处于最佳的反应条件，催化剂介绍了 100% 山梨糖醇变换和超过 48% 乙二醇(例如并且 1,2-PG ) 产量。polyols (山梨糖醇，木糖醇和甘油) 的动力学学习 hydrogenolysis 证明有更多的氢氧根数字的 polyols 举办更高的活动，产品分发是运动平衡的最后的结果，它能给我们关于怎么改变产品选择的某灵感。
英文摘要：
A series of Ni based catalysts with different supports and basic additives were prepared by sequential impregnation method. The catalysts were characterized by XRD, BET, H2-TPR and CO2-TPD techniques. It was found that the introduction of basic additives enhanced the basicities of catalyats and promoted the dispersities of Ni particles by strong interaction between Ni2＋ and basic additives. Among the Ni based catalysts, 10%Ni/10%La203/ZrO2 showed the superior performance in sorbitol hydrogenolysis. The synergistic effect of Ni and La203 was proven to play an essential role in selective synthesis of EG and 1,2-PG. In the optimal reaction condition, the catalyst presented 100% sorbitol conversion and over 48% glycols （EG and 1,2-PG） yield. The kinetics study of polyols （sorbitol, xylitol and glycerol） hydrogenolysis showed that polyols with more hydroxyl number have higher activity and products distribution was final results of kinetic balance, which could give us some inspiration abeut how to change the products selectivity.
