A xylene isomerization process is disclosed in which any ethylbenzene in the
feed
is removed, either by dealkylation or isomerization, in a separate reactor upstream
of the xylene isomerization reactor and the xylene isomerization catalyst is contained
in the same reactor, typically a clay treater, as that used to accommodate the
olefin removal catalyst. In certain cases, a single catalyst may be used to effect
both xylene isomerization and olefin removal.
