| Abstract: | The acidic property of Ru-Re/SiO2 catalysts and the role of Re were investigated.The acidic properties of Ru-Re/SiO2,Ru/SiO2, and Re/SiO2 were characterized by temperature programmed desorption of ammonia and in situ IR spectra of pyridine adsorption.Their catalytic performances in glycerol hydrogenolysis were compared.Ru-Re/SiO2,Ru/SiO2,and Re/SiO2 possessed acid sites,but the site amounts of Ru-Re/SiO2 and Re/SiO2 were much higher than that of Ru/SiO2.The activities of Ru-Re/SiO2 with different Re content... |
