摘要： 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.
