    • PROBLEM TO BE SOLVED: To provide a method for isomerization of a hydrocarbon mixture containing 7C and 8C saturated hydrocarbons (so-called heavy naphtha).
      SOLUTION: A hydrocarbon mixture containing at least 50 wt.% of 7C and 8C saturated hydrocarbons is brought into contact with a solid acid catalyst comprising a sulfuric acid component and platinum-group metal component, carried on a carrier containing a zirconia part and alumina part, in the presence of hydrogen at a reaction temperature of 130-160°C. The solid acid catalyst preferably used comprises one of which the zirconia part contains a tetragonal crystal zirconia, the alumina part contains γ-alumina, and the platinum-group metal component is crystallized.

    • PROBLEM TO BE SOLVED: To provide a simulation method which makes it possible to accurately estimate the deterioration of the activity of a hydrorefining catalyst due to the deposition of metal without using any special catalyst evaluation technique.
      SOLUTION: In evaluating a catalyst, (a) the reaction rate constant of each refining object component, obtained from a change in concentration of each refining object component in a hydrocarbon oil and (b) the concentrations of refining object metal components contained in the catalyst at two or more different places at two or more times in a reactor are measured, and the measurements are applied to a numerical formula model, in which the reaction rate of each refining object component changes based on the concentration of the refining object metal component contained in the catalyst, to extract a deterioration function parameter. The numerical formula model using the deterioration function parameter is used to calculate the rate of reaction of each refining object component in hydrorefining and the change in the refining object metal component contained in the catalyst with time.

    • 要解决的问题:提供一种模拟方法,其可以精确地估计由于金属沉积而导致的加氢精制催化剂的活性的劣化,而不使用任何特殊的催化剂评价技术。 解决方案:在评价催化剂时,(a)由烃油中的每个精制对象成分的浓度变化而得到的各精炼对象成分的反应速度常数,(b)催化剂中所含的精炼对象金属成分的浓度 在反应器中在两次以上的两个以上的不同位置进行测定,并且将测量值应用于数值公式模型,其中每个精炼对象组分的反应速率基于所含的精炼对象金属组分的浓度而变化 在催化剂中,提取劣化函数参数。 使用劣化函数参数的数值公式模型用于计算加氢精制中的每个精炼对象组分的反应速率和催化剂中所含的精炼对象金属组分随时间的变化。
