Methods and corresponding catalysts are provided for transalkylation of 1 ring (Cci +) aromatic compounds, for example to obtain para-xylene and / or other xylenes. Preferred catalysts include molecular sieves having a three-dimensional 12-membered ring framework structure, molecular sieves having a one-dimensional 12-membered ring framework structure, acidic microporous materials having a channel pore size of at least 6.0 angstroms, and / or Or molecular sieves having the MWW framework structure. The method comprises performing a transalkylation, wherein at least a portion of the feed to the transalkylation process is in the liquid phase. The transalkylation conditions may correspond to the conditions in which the continuous liquid phase is present in the reaction environment. Some embodiments include liquid phase transalkylation methods for naphthalene containing feed streams.
