Abstract
A catalyst for transforming aromatic hydrocarbons, preferably for dismutation of toluene to produce benzene and xylenes and transalkylation of toluene and aromatic compounds containing at least 9 carbon atoms per molecule, preferably trimethylbenzenes, to produce xylenes, contains a mordenite in its acid form in a proportion of 40% to 90% by weight and a binder, which is preferably alumina, and which is generally present in a proportion of 10% to 60% by weight. The mordenite contains less than 0.1% by weight of sodium and has a SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of over 40-60.
