    • A solid acid catalyst which contains a porous catalyst pellet exhibiting solid acid properties and a platinum group metal component carried on the catalyst pellet and can be used in an acid-catalyzed reaction, wherein it has a platinum group metal component distribution therein such that a value obtained by dividing a standard deviation of concentrations of the platinum group metal component by an average concentration is 0.4 or less; a method for preparing the solid acid catalyst which comprises providing a solution to be carried containing a platinum group metal as a cation and impregnating a crystalline porous catalyst pellet exhibiting solid acid properties with the solution to be carried; and a method for isomerizing a hydrocarbon which comprises contacting a hydrocarbon stock containing 70 wt % or more of saturated hydrocarbon components having 4 to 10 carbon atoms with the solid acid catalyst. The above solid acid catalyst having an above specified distribution of a platinum group metal component exhibits an enhanced catalyst activity.
    • 一种固体酸催化剂,其含有表现出固体酸性质的多孔催化剂颗粒和载于催化剂颗粒上的铂族金属组分,可用于酸催化反应,其中铂族金属组分分布在其中,使得值 通过将铂族金属成分的浓度的标准偏差除以平均浓度而得到的值为0.4以下; 一种制备固体酸催化剂的方法,其包括提供含有铂族金属作为阳离子的载体溶液,并用待携带的溶液浸渍显示固体酸性质的结晶多孔催化剂颗粒; 和烃的异构化方法,其包括使含有70重量%以上的具有4〜10个碳原子的饱和烃成分的烃原料与固体酸催化剂接触。 具有上述特定分布的铂族金属组分的上述固体酸催化剂表现出提高的催化剂活性。
