Patent ID: 8207388

Claim:
A transalkylation process, comprising: contacting an aromatic hydrocarbon mixture comprising one or more polyalkylated aromatic hydrocarbons and a non-alkylated aromatic hydrocarbon with a catalytic composition, to thereby transalkylate, in the liquid phase, one or more alkyl groups from the polyalkylated aromatic hydrocarbons to the non-alkylated aromatic hydrocarbon and form a mono-alkylated aromatic hydrocarbon, wherein the catalytic composition, comprises: a zeolite and an inorganic binder, wherein the zeolite is zeolite Y having a SiO 2 /Al 2 O 3 molar ratio of from 10 to 20, and the binder is γ-alumina, wherein said catalytic composition has a pore volume, obtained by adding the mesoporosity and macroporosity fractions present in the catalytic composition, of greater than or equal to 0.7 cc/g, wherein at least 30% of said pore volume consists of pores with a diameter greater than 100 nanometers.
