    • Selective hydrogenation process comprising: • contacting in the presence of hydrogen an hydrocarbon feedstock comprising at least one unsaturated compound selected from the group consisting of al kynes and dienes and mixtures thereof with a first hydrogenation catalyst in a first reaction zone to produce a first product stream having a reduced proportion of alkynes and/or dienes; and • contacting the first product stream in a second reaction zone having an inlet and an outlet, in the presence of optional additional hydrogen, with a second hydrogenation catalyst to produce a second product stream, wherein, the first hydrogenation catalyst comprises: • a first constituent of at least one metal or metal-based component selected from the elements consisting of Groups 1-10 of the Periodic Table of Elements (new IUPAC notation) and optionally a second constituent of at least one metal or metal-based component selected from the elements consisting of Groups 11-14 of the Periodic Table of Elements, and said first constituent and optional second constituent are on a carrier made essentially of SiC or of an alkaline earth metal silicate. Hydrogenation catalyst comprising : • a first constituent of at least one metal or metal-based component selected from the elements consisting of Groups 1-10 of the Periodic Table of Elements (new IUPAC notation) and a second constituent of at least one metal or metal-based component selected from the elements consisting of Groups 11 -14 of the Periodic Table of Elements, and • said first constituent and second constituent are on a carrier made essentially of an alkaline earth metal silicate or of SiC, • the second constituent is optional if the carrier is made essentially of SiC.
    • 选择性氢化方法包括:·在氢气存在下,使包含至少一种选自烷烃和二烯烃的不饱和化合物和它们的混合物的烃原料与第一氢化催化剂在第一氢化催化剂 反应区以产生具有减少的炔烃和/或二烯烃比例的第一产物流; 和·使第一产物流在具有入口和出口的第二反应区中在存在任选的额外氢气的情况下与第二氢化催化剂接触以产生第二产物流,其中第一氢化催化剂包含:·第一 至少一种选自元素周期表第1-10族的元素(新的IUPAC符号)的金属或基于金属的组分的组分和任选的第二组分选自至少一种金属或金属基组分,所述金属或金属基组分选自 由元素周期表第11-14族组成的元素,并且所述第一组分和任选的第二组分在基本上由SiC或碱土金属硅酸盐制成的载体上。 氢化催化剂包括:·选自元素周期表第1-10族(新的IUPAC符号)的至少一种金属或金属基成分的第一成分和至少一种金属或金属 - 基元素,其选自元素周期表第11-14族的元素,以及·所述第一成分和第二成分在基本上由碱土金属硅酸盐或SiC制成的载体上,·第二成分是可选的 如果载体基本由SiC制成。
