Patent ID: 7872166

Claim:
A process for isomerising a feed comprising at least one aromatic compound containing eight carbon atoms per molecule carried out in the presence of at least one catalyst comprising at least one modified zeolite with structure type EUO, at least one binder and at least one metal from group VIII of the periodic table, said catalyst having been prepared by a process which comprises at least the following steps in succession: a) a step for treatment of a zeolite with structure type EUO in the presence of at least one molecular compound containing at least one silicon atom, during which said compound, with a diameter greater than the maximum pore opening diameter in said zeolite, is deposited in the gas phase in the absence of any hydrocarbon compound on the outer surface of said zeolite; b) at least one heat treatment step sufficient to decompose said molecular compound in step a) to amorphous silica on the outer surface of said zeolite to form a modified zeolite; c) a step for forming said modified zeolite with a binder; d) at least one step for introducing at least one metal from group VIII of the periodic table onto a support comprising resultant modified and formed zeolite.
