    • A process is described for isomerising an aromatic cut containing at least one aromatic compound containing eight carbon atoms per molecule, comprising bringing said cut into contact with a catalyst containing a zeolite with structure type EUO, said catalyst having been prepared using a process comprising at least the following steps: i) synthesizing at least one zeolite with structure type EUO having an overall Si/Al atomic ratio in the range 5 to 45; ii) dealuminating the zeolite obtained at the end of said step i) using at least one treatment with an aqueous solution of a mineral acid or an organic acid, such that at least 10% by weight of the aluminium atoms are extracted from said zeolite from said step i); iii) forming said dealuminated zeolite with a matrix; iv) depositing at least one metal from group VIII of the periodic table of the elements, the order of carrying out said steps iii) and iv) being inconsequential following on from said step ii).
    • 描述了一种方法,用于异构化含有至少一种每分子含有8个碳原子的芳族化合物的芳族切割,包括使所述切割物与含有结构类型为EUO的沸石的催化剂接触,所述催化剂已经使用至少包括 以下步骤:i)合成至少一种具有总体Si / Al原子比在5至45范围内的结构类型EUO的沸石; ii)使所述步骤i)末端获得的沸石脱铝,使用无机酸或有机酸的水溶液进行至少一次处理,使得至少10重量%的铝原子从所述沸石中提取出来 说步骤i); iii)用基质形成所述脱铝沸石; iv)从所述元件的周期表的VIII族中沉积至少一种金属,执行所述步骤iii)和iv)的顺序在所述步骤ii)之后是无关紧要的。
