    • A selective hydrogenation catalyst system, and a process for its preparation and its use. The catalyst system of the invention comprises a support material, a Pd-containing catalyst component and a Bi-containing cocatalyst component. The catalyst system of the invention is manufactured by impregnating the support material simultaneously or separately with Pd-containing solution, Bi-containing solution or/and one or more other cocatalyst solutions, and then drying and calcining. The activity and selectivity of the catalyst system of the invention, in selective hydrogenation of acetylenic and diolefmic compounds in hydrocarbon feeds, are significantly improved, while the green oil formation and carbon deposit on the catalyst reduced, and the service life increased and production costs decreased.
    • 选择性氢化催化剂体系及其制备方法及其应用。 本发明的催化剂体系包括载体材料,含Pd催化剂组分和含Bi助催化剂组分。 本发明的催化剂体系是通过与含Pd溶液,含Bi的溶液或一种或多种其它助催化剂溶液同时或分开地浸渍载体材料,然后干燥和煅烧来制造的。 本发明的催化剂体系在烃类进料中炔属和二烯化合物的选择性氢化中的活性和选择性得到显着提高,而催化剂上的绿色油形成和碳沉积减少,使用寿命增加,生产成本降低 。
