    • The present invention concerns a catalyst which contain at least one zeolite with structure type NES, preferably NU-87, comprising silicon and at least one element T selected from the group formed by aluminium, iron, gallium and boron. Preferably, element T has been extracted so that the overall Si/T atomic ratio is more than 20. This zeolite is at least partially in its acid form. The binder is preferably alumina. The catalyst also contains at least one metal selected from the group formed by group VIIB, group VIB and iridium, preferably rhenium. Finally, the catalyst optionally also contains at least one metal selected from the group formed by elements from groups III and IV of the periodic table, preferably indium or tin. The present invention also concerns the use of the catalyst in a process for transalkylating alkylaromatic hydrocarbons such as toluene and alkylaromatic compounds containing at least 9 carbon atoms. In particular, this catalyst is highly effective in treating C9+ aromatic feeds containing more than 5% by weight of aromatic olefins containing 10 carbon atoms and more, this feed possibly also containing benzene.
    • 本发明涉及含有至少一种结构类型为NES,优选为NU-87的沸石的催化剂,其包含硅和选自由铝,铁,镓和硼形成的基团中的至少一种元素T. 优选地,提取元素T使得总Si / T原子比大于20.该沸石至少部分为其酸形式。 粘合剂优选为氧化铝。 该催化剂还含有选自由ⅦB族,ⅥB族和铱族,优选铼形成的族中的至少一种金属。 最后,催化剂任选地还含有至少一种选自元素周期表III和IV族的元素形成的金属,优选为铟或锡。 本发明还涉及催化剂在烷基化烷基芳烃如甲苯和含有至少9个碳原子的烷基芳族化合物的方法中的用途。 特别地,该催化剂在处理含有大于5重量%的含有10个碳原子的芳族烯烃和更多的芳族烯烃的C9 +芳族原料方面是非常有效的,该进料还可能含有苯。

    • The present invention concerns a process for preparing a zeolite with structure type EUO comprising at least one element X selected from silicon and germanium and at least one element T selected from iron, aluminium, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese, characterized in that seeds of at least one zeolitic material are used comprising at least one element X′ selected from silicon and germanium and at least one element T′ selected from iron, aluminium, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese with a ratio X′/T′ of less than 200, said seeds being different from the zeolite with structure type EUO being prepared. The present invention also concerns the use of the zeolite obtained as a catalyst in a process for converting hydrocarbon-containing feeds, as an adsorbent to control pollution and as a molecular sieve for separation, and more particularly as a catalyst in a process for isomerizing aromatic compounds containing 8 carbon atoms.
