    • The catalyst comprises a physical particle-form mixture of a Componet A, a Component B, and a Component C, said Component A comprising at least one Group VIII noble metal, preferably platinum, deposed on a solid catalyst support material providing acidic catalytic sites, said Component B comprising a small amount of a non-noble metal of Group VIII selected from cobalt, nickel, and mixtures thereof, preferably cobalt, on a solid catalyst support material providing acidic catalytic sites, said Component C comprising a small amount of gallium deposed on a solid catalyst support material providing acidic catalytic sites, and said catalyst having been prepared by thoroughly and intimately blending finely-divided particles of said Component A, B, and C to provide a thoroughly-blended composite.The catalyst can be employed suitably in a hydrocarbon conversion process. In particular, the catalyst can be employed in a process for the reforming of a hydrocarbon stream, which process comprises contacting said stream in a reforming zone under reforming conditions and in the presence of hydrogen with said catalyst. The process can be used advantageously to reform a hydrocarbon stream that contains up to 80 ppm sulfur.
    • 所述催化剂包括组分A,组分B和组分C的物理颗粒形式的混合物,所述组分A包含至少一种第八族贵金属,优选铂,其沉积在提供酸性催化位点的固体催化剂载体材料上, 所述组分B包含少量选自钴,镍及其混合物,优选钴的非贵金属的第Ⅷ族,在提供酸性催化位点的固体催化剂载体材料上,所述组分C包含少量镓, 在提供酸性催化位点的固体催化剂载体材料上,并且所述催化剂通过将所述组分A,B和C的细碎颗粒彻底和紧密地混合以提供充分混合的复合材料制备。 催化剂可以在烃转化方法中适当地使用。 特别地,催化剂可以用于烃流重整的方法中,该方法包括在重整条件下和氢气存在下将所述物流在重整区中与所述催化剂接触。 该方法可有利地用于重整含有高达80ppm硫的烃流。
