Abstract
Systems and methods are provided for forming para-xylene from aromatics-containing streams having reduced or minimized amounts of C2+ side chains. Reduced or minimized amounts of C2+ 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.
