摘要
采用共沉淀法制备Al2 O3-TiO2 混合载体。该载体具有较大的比表面积 ,用其制备的钯系催化剂对于炔烃和二烯烃的选择加氢具有较高的加氢活性和选择性。XRD结果表明 ,混合载体中Al2 O3 为无定形 ,TiO2 为 β型。
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.
