Disclosed are selectivated transalkylation catalyst compositions and methods of making the same. The selectivated transalkylation catalyst compositions have a zeolite framework structure of MWW, FAU, BEA*, or MOR, or mixtures thereof, and are selectivated with a selectivating solution. The selectivating solution includes a dissolved ion of at least one element in Group 1, Group 2, Group 15, Group 16, or Group 17 of the Periodic Table. Also disclosed are processes of producing ethylbenzene and cumene using the selectivated transalkylation catalyst compositions.
