Abstract
It is desirable to provide improved processes and apparatuses for methylation of aromatic compounds such as toluene and benzene in an aromatics complex. Described herein are processes and apparatuses for methylation of aromatics in an aromatics complex for producing a xylene isomer product. More specifically, processes and apparatuses for producing para-xylene by the selective methylation of toluene and/or benzene in an aromatics complex.
