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.

Claim (Index 1):
A process for the methylation of toluene, comprising:\n passing a toluene feed stream and a plurality of methanol feed streams to an alkylation reaction zone comprising an alkylation catalyst comprising at least one MWW, UZM-8, or UZM-37 zeolite where external acid sites have been removed by steaming or by contacting with an Al-chelating agent at alkylation reaction conditions to produce an alkylation reaction zone product stream having an increased ratio of para-xylene to xylenes compared to an untreated MWW, UZM-8, or UZM-37 zeolite, wherein the alkylation reaction conditions comprise a temperature of about 200\u00b0 C. to about 400\u00b0 C. and a pressure of about 15 psig to about 400 psig; separating the alkylation reaction zone product stream into a vent gas stream, an overhead steam comprising toluene and xylenes, a side cut comprising xylenes, and a bottoms stream comprising C9+, containing diphenylmethane; and passing the bottoms stream to a transalkylation zone.
