Abstract: The invention relates to the hydrocarbon upgrading to produce aromatic hydrocarbon, to equipment and materials useful in such upgrading, and to the use of such upgrading for, e.g., producing aromatic hydrocarbon natural gas. The upgrading can be carried out in the presence of a dehydrocyclization catalyst comprising at least one dehydrogenation component and at least one molecular sieve.

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.
