Process for the production of xylene |
| abstract |
In the production process of para-xylene, a feed comprising a C 6+ aromatic carbon pixel is separated into a toluene-containing stream, a C 8 aromatic hydrocarbon-containing stream and a C 9+ aromatic hydrocarbon-containing stream. The toluene-containing stream is contacted with a methylating agent to convert the toluene to xylene to produce a methylated effluent stream. The para-xylene is recovered from the C 8 aromatic hydrocarbon-containing stream and the methylated effluent stream in the para-xylene recovery section to produce a para-xylene depleted stream, which is then separated from the para-xylene depleted stream Is contacted with the xylene isomerization catalyst under liquid phase conditions effective to isomerize the xylene in the isomerization stream to produce an isomerization stream. The C 9+ -containing stream is contacted with a transalkylation catalyst under conditions effective to convert the C 9+ aromatic to a C 8 -aromatic to produce a transalkylation stream, the transalkylation stream comprising para-xylene recovery Section. |
