Process for producing xylene |
| abstract |
In a process for producing para-xylene, a toluene-containing stream is contacted with a methylating agent under conditions effective to convert toluene to xylene and produce a methylated effluent stream. Para-xylene is recovered from the methylated effluent stream to produce a xylene-depleted stream and a portion of the xylene-depleted stream is contacted with a xylene isomerization catalyst under liquid phase isomerization conditions effective to produce a first isomerized stream while a portion of the xylene-depleted stream is contacted with a xylene isomerization catalyst under vapor phase isomerization conditions effective to produce a second isomerized stream. The first and second isomerized streams are then recycled to the para-xylene recovery step. |
