| Abstract: | The coprecipitated Al 2O 3-TiO 2 support with large surface area was prepared and characterized by XRD and pore distribution by mercury intrusion.Hydrogenation catalyst using this support has high activity and selectivity.The result of XRD indicates that aluminium oxide in Al 2O 3-TiO 2 is amorphous and titanium oxide is β-TiO 2.The characteristics of mixed Al 2O 3-TiO 2 renders a large capacity for enduring sulphide and arsenide to Pd catalyst for selective hydrogenation. |
