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: Systems and methods are provided for upgrading blends of catalytic slurry oil and steam cracker tar to form fuel and/or fuel blending products. The steam cracker tar can optionally correspond to a fluxed steam cracker tar that includes steam cracker gas oil and/or another type of gas oil or other diluent. It has been unexpectedly discovered that blends of catalytic slurry oil and steam cracker tar can be hydroprocessed under fixed bed conditions while reducing or minimizing the amount of coke formation on the hydroprocessing catalyst and/or while reducing or minimizing plugging of the fixed bed, as would be conventionally expected during fixed bed processing of a feed containing a substantial portion of steam cracker tar. Additionally or alternately, it has been unexpectedly discovered that formation of coke fines within steam cracker tar can be reduced or minimized by blending steam cracker tar with catalytic slurry oil.

Abstract: The invention relates to the conversion of light hydrocarbon to higher-value hydrocarbon, such as aromatic hydrocarbon, to equipment and materials useful in such conversion, and to the use of such conversion for, e.g., natural gas upgrading. The conversion can be carried out in two stages, with each stage containing a dehydrocyclization catalyst comprising at least one dehydrogenation component and at least one molecular sieve.

Abstract: Methods are provided for forming aromatic compounds from a highly unsaturated aliphatic feeds optionally in combination with methanol. The method can include dehydrogenating a feed containing at least about 50 vol % C1-C4 alkanes under dehydrogenation conditions to form a dehydrogenation effluent containing at least about 25 vol % alkynes. Alternatively, other sources of alkyne-containing feeds can be used. At least a portion of the alkyne-containing feed can then be converted under effective conversion conditions to form a conversion effluent comprising a hydrocarbon product containing aromatic compounds.

Exemplary processes include providing a first mixture comprising ?10 wt % of at least one oxygenate; contacting at least a portion of the first mixture with a methanol conversion catalyst under suitable conditions including a first pressure, P1, to yield an intermediate composition including olefins having at least two carbon atoms; introducing at least a portion of the intermediate composition to an oligomerization catalyst under suitable conditions including a second pressure, P2, to yield an effluent mixture comprising gasoline boiling range components and distillate boiling range components; and recovering at least a portion of the gasoline boiling range components and distillate boiling range components. The first and second pressure can be relatively similar. Apparatus and systems for carrying out the disclosed processes are also described.

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.
