Brandon O'Neill - Lebanon NJ, US

International Classification:

C07C 1/20
B01J 8/04
C07C 2/12

Abstract:

Processes for forming refined hydrocarbons are disclosed. 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, P, 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, P, 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.

International Classification:

C07C 1/22

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, CO, 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.

International Classification:

C07C 1/24
C07C 2/64
C07C 6/00

Abstract:

Processes for catalytically converting oxygenates to hydrocarbon products having an increased C-Caromatics content therein. A first mixture comprising ≧10.0 wt. % of at least one oxygenate, based on the weight of the first mixture, contacts a catalyst in a fluidized bed reactor to produce a product stream including water, one or more hydrocarbons comprising ≧30.0 wt. % of aromatics, based on the weight of the hydrocarbons in the product stream, hydrogen, and one or more oxygenates. The catalyst comprises at least one molecular sieve, a binder, and at least one element selected from Groups 2-14 of the Periodic Table. At least one water-rich stream, at least one aromatic-rich hydrocarbon stream, and at least one aromatic-depleted hydrocarbon stream are separated from the product stream, and at least a portion of one of the aromatic-rich hydrocarbon stream or the aromatic-depleted hydrocarbon stream is recycled back to the reactor.
