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.

Abstract: This disclosure relates to the production of xylenes from syngas, in which the syngas is converted to an aromatic product by reaction with a Fischer-Tropsch catalyst and an aromatization catalyst. The Fischer-Tropsch catalyst and aromatization catalyst may be different catalysts or combined into a single catalyst. The aromatic product is then subjected to selective alkylation with methanol and/or carbon monoxide and hydrogen to increase its p-xylene content.

Abstract: A catalyst system and processes for combined aromatization and selective hydrogen combustion of oxygenated hydrocarbons are disclosed. The catalyst system contains at least one aromatization component and at least one selective hydrogen combustion component. The process is such that the yield of hydrogen is less than the yield of hydrogen when contacting the hydrocarbons with the aromatization component alone.

Abstract: Methods are provided for conversion of methanol and/or dimethyl ether to aromatics, such as a para-xylene, and olefins, such as ethylene and propylene. The methods can be used in conjunction with molecular sieve (zeolite) catalysts that are prepared for use in conjunction with selected effective conversion conditions. The combination of a catalyst and a corresponding effective conversion condition can allow for improved yield aromatics and olefins generally; improved yield of desired aromatics and olefins, such as para-xylene, ethylene, and/or propylene; reduced production of less desirable side products, such as methane, CO, CO2, and/or coke; or a combination thereof. The preparation of the catalyst can include modification of the catalyst with a transition metal, such as Zn or Ga. The preparation of the catalyst can also include steaming of the catalyst. In some aspects, the preparation of the catalyst can further include modifying the catalyst with phosphorous.

Abstract: A fluidized bed process for producing para-xylene via toluene and/or benzene methylation with methanol using a dual function catalyst system. A first catalyst accomplishes the toluene and/or benzene methylation and a second catalyst converts the by-products of the methylation reaction or unconverted methylating agent, improves the yields of the desired products, or a combination thereof. The inclusion of the second catalyst can suppress the C1-C5 non-aromatic fraction by over 50% and significantly enhance the formation of aromatics.
