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 to produce xylenes, contains 40% to 90% by weight of a mordenite in its acid form in a proportion of and 10% to 60% by weight of binders. The mordenite comprises less than 0.1% by weight of sodium and has a Si02/A2O3 molar ratio of over 70. The catalyst also contains at least one metal from groups VI, VII or VIII and optionally an additional metal from groups III or IV.
