Abstract
This present disclosure relates to processes for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, the present disclosure relates to a process for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex using mild reaction conditions, namely a combination of low temperatures and elevated pressures using a zeolite with lower number of external acid sites.
