Abstract:
Systems and methods are provided for forming para-xylene from aromatics-containing streams having reduced or minimized amounts of C 2+  side chains. Reduced or minimized amounts of C 2+  side chains can provide benefits for improving and/or allowing modification of transalkylation conditions, xylene isomerization conditions, or a combination thereof. Such aromatics-containing streams can be formed, for example, by conversion of methyl halide, methanol, syngas, and/or dimethyl ether to aromatics by an aromatic conversion process. The methyl halide, methanol, syngas, and/or dimethyl ether can be formed by conversion of methane.

Claim (Index 19):
A method for forming para-xylene, comprising:\n a) separating a first C 8  aromatics stream and a C 9 + aromatics stream from an aromatic hydrocarbon feed stream having an ethylbenzene content of 5 wt % or less based on the total aromatics content of the aromatic hydrocarbon feed stream; b) separating a first para-xylene enriched fraction and a first para-xylene depleted fraction from the first C 8  aromatics stream using a simulated moving bed separator, the para-xylene enriched fraction having a greater weight percent of para-xylene than the weight percent of para-xylene in the first C 8  aromatics stream; c) separating a separation purge stream from the first para-xylene depleted stream, wherein the weight ratio of the separation purge stream to the first para-xylene enriched fraction being 0.2 or less; and d) isomerizing the para-xylene depleted fraction under effective liquid phase isomerization conditions to form an isomerized product stream having a greater weight percent of para-xylene than the weight percent of para-xylene in the para-xylene depleted fraction.
