Effect of different supports for copper as catalysts on glycerol hydrogenolysis to 1,2-propanediol

In this work, several copper supported catalysts, Cu/Dol, Cu/Al2O3, Cu/Bent, Cu/Mont, and Cu/Talc were prepared using wet impregnation route characterized BET, BJH, XRD, H2-TPR, NH3–TPD, SEM analytical techniques subsequently tested in hydrogenolysis of glycerol to 1,2-propanediol (1,2-PDO). The nature support was found determine the activation catalysts. Among dolomite catalyst (Cu/Dol) exhibited superior performance due species mutual interaction. findings from various characterization tests showed that presence essentially enriched on grain surfaces, redox properties, acidic property enhanced, as well formation small size contributed high conversion (78.5%) 1,2-PDO selectivity (79%) with low methanol production by-product at 200 °C, 4 MPa H2 10 h reaction conditions.
