Abstract
A process for isomerization of an aromatic fraction that contains at least one aromatic compound that has eight carbon atoms per molecule is described, with said process comprising bringing said fraction into contact with a catalyst that comprises at least one hydrogenating-dehydrogenating metal that is selected from the group that is formed by the metals of group VIB and group VIII of the periodic table and a composite that is formed by a zeolite that is selected from among the EUO-, MTW- and MOR-structural type zeolites and silicon carbide SiC.

Process for isomerization of an aromatic fraction that contains at least one aromatic compound that has eight carbon atoms per molecule, whereby said process comprises bringing said fraction into contact with a catalyst that comprises at least one hydrogenating-dehydrogenating metal that is selected from the group that is formed by the metals of group VIII of the periodic table, and a composite substrate that comprises silicon carbide SiC and a zeolite that is selected from among the EUO-, MTW-, and MOR-structural type zeolites, taken by itself or in a mixture.
