Embodiments disclosed herein include a process for producing paraxylene and catalyst for use in processes for producing paraxylene. In an embodiment, the process includes contacting an aromatic hydrocarbon feed comprising benzene and/or toluene with an alkylating reagent comprising methanol and/or dimethyl ether in at least one alkylation reaction zone in the presence of an alkylation catalyst comprising a molecular sieve having a Constrain Index less than 5 and under alkylation conditions. The alkylation catalyst comprises at least one of a rare earth metal or alkaline earth metal and a binder, and a majority of the at least one rare earth metal or alkaline earth metal is deposited on the molecular sieve. In addition, the process includes producing an alkylated aromatic product comprising xylenes.
