ABSTRACT:
This invention relates to a catalyst that contains at least one BOG-structured zeolite that comprises silicon and at least one Element T that is selected from the group that is formed by aluminum, iron, gallium and boron. The catalyst contains at least one metal that is selected from the group that is formed by the non-noble elements of groups VIB, VIIB and VIII of the periodic table. Said catalyst is used in a process for transalkylation of alkyl-aromatic hydrocarbons such as toluene and the alkyl-aromatic compounds with at least 9 carbon atoms.
