    • A sulfated solid catalyst is provided which comprises (1) oxide or hydroxide of Group III or Group IV element, e.g. zirconium, and (2) a first metal comprising a metal or combination of metals selected from the group consisting of platinum, palladium, nickel, platinum and rhenium, and platinum and tin. The catalyst may further comprise (3) a second metal selected from the group consisting of Group VIII elements, e.g. iron. One embodiment of the invention further comprises (4) a third metal selected from the group consisting of Group V, VI and VII elements, e.g. manganese. The catalyst of the invention is useful for the isomerization of normal alkanes having 4 to 40 carbon atoms per molecule, for the naphtha upgrading of a hydrocarbon feedstock and for the hydrocracking of a hydrocarbon feedstock.
    • 提供硫酸化固体催化剂,其包含(1)III族或IV族元素的氧化物或氢氧化物,例如 锆,和(2)包含选自铂,钯,镍,铂和铼的金属或金属组合的第一金属,以及铂和锡。 催化剂还可以包含(3)选自VIII族元素的第二种金属,例如。 铁。 本发明的一个实施方案还包括(4)选自第V,VI和VII族元素的第三种金属,例如。 锰。 本发明的催化剂可用于每分子具有4至40个碳原子的正构烷烃异构化,用于烃原料的石脑油升级和烃原料的加氢裂化。
