    摘要： A method of isomerizing a hydrocarbon, comprising, in the presence of hydrogen, bringing a hydrocarbon containing C7 or C8 saturated hydrocarbons (known as heavy naphtha) in a proportion of 50 wt.% or more into contact with a solid acid catalyst having a platinum group metal component borne on a support, the support comprising as metal components at least one Group IV metal component selected from the group consisting of titanium, zirconium and hafnium and at least one Group VI metal component selected from the group consisting of tungsten and molybdenum. This isomerization is preferably performed at 190 to 250 ° C under a pressure of 0.8 to 10 MPa. With respect to the catalyst, a solid acid catalyst wherein the support further comprises aluminum as a metal component is preferably used.

    摘要： A catalyst for hydrofining treatment which comprises a carrier comprising a porous inorganic oxide, 0.1 to 25 wt % of at least one metal element being active for hydrogenation selected from among the elements belonging to Groups 6, 8, 9 and 10 of the Periodic Table and 0.1 to 3 wt % of potassium, wherein the metal element being active for hydrogenation has a concentration distribution such that its concentration is higher at central portions of the catalyst than in outer regions and the potassium component has a concentration distribution such that its concentration is higher in outer regions than in central portions. The catalyst is free from the problem that pores present in the surface region of the catalyst are blocked by metal-containing components contained in hetero compound components and thus allows the hetero compound components to diffuse into the inside of grains thereof, which results in keeping a high catalytic activity for a long period of time.

    摘要翻译： 一种加氢精制处理用催化剂，其特征在于，含有载体，该载体含有多孔性无机氧化物，0.1〜25重量％选自元素周期表第6,8,9和10族元素中的至少一种对氢化有活性的金属元素和 0.1至3重量％的钾，其中对氢化有活性的金属元素具有浓度分布，使得其浓度在催化剂中心部分高​​于在外部区域，并且钾成分具有浓度分布使得其浓度高于 在外部区域比在中央部分。 该催化剂不存在以下问题：存在于催化剂的表面区域中的孔隙被包含在异质化合物组分中的含金属成分所阻断，并因此使杂化合物成分扩散到其晶粒内部，这导致保持 高的催化活性很长一段时间。
