A catalyst for converting C9+ aromatics to lighter aromatics includes a metallic function derived from a metal such as platinum constrained within cages and/or channels of a microporous material, such as chabazite, wherein the cages and/or channels of the microporous material are defined by 8 tetrahedral atoms or fewer; and an acidic function derived from an additional zeolite having cages and/or channels defined by 10 or more tetrahedral atoms, wherein the microporous material providing the metallic function and additional zeolite providing the acidic function are coupled by a binder. Un catalyseur pour convertir des composés aromatiques en C9 + en aromatiques plus légers comprend une fonction métallique dérivée d'un métal tel que le platine contraint à l'intérieur de cages et/ou de canaux d'un matériau microporeux, tels que la chabazite, les cages et/ou les canaux du matériau microporeux étant définis par 8 atomes tétraédriques ou moins ; et une fonction acide dérivée d'une zéolite supplémentaire ayant des cages et/ou des canaux définis par 10 atomes tétraédriques ou plus, le matériau microporeux fournissant la fonction métallique et la zéolite supplémentaire fournissant la fonction acide étant couplés par un liant.
