It takes three: Ni and Cu mono- and bimetallic catalysts modified with various types of acid oxides MO_x are tested for the hydrogenolysis of glycidol as an alternative route to the hydrogenolysis of glycerol to obtain 1,3-propanediol. The presence of modifiers affected the dispersion and reducibility of the NiO particles and the strength and amount of acid sites. Among the modifiers tested, Re leads to the highest activity, a high propanediols selectivity, and the highest 1,3-propanediol/1,2-propanediol ratio.

使用酸介孔皂石负载的MOx修饰的镍-铜催化剂，通过缩水缩水制缩水甘油作为选择性获得1,3-丙二醇的替代途径

这需要三个步骤：测试了用各种类型的氧化物氧化物MO _x改性的Ni和Cu单金属和双金属催化剂对缩水甘油进行氢解的可能性，这是甘油氢解获得1,3-丙二醇的另一种方法。改性剂的存在会影响NiO颗粒的分散性和还原性以及酸性位点的强度和数量。在测试的改性剂中，Re导致最高的活性，较高的丙二醇选择性和最高的1,3-丙二醇/ 1,2-丙二醇比。
