Glycerol (GLY) hydrogenolysis is a reaction sensitive to the structure of the catalyst. Themain products obtained are acetol, 1,3-propanediol (1,3-PDO) and 1,2- propanediol (1,2-PDO),where the selective production of any of them depends on acid-base features of media and/orcatalyst surface and metal-support interactions [1]. In general, supports give acid-base featuresneeded in the reaction while metal sites provide the bond-breaking capacity. This workproposes to evaluate the effect of modifying the acid character of alumina by adding oxideswith different acid-base features (MgO and/or ZnO) and thus the interaction of Cu with obtainedsupports in the selectivity of GLY hydrogenolysis.
