METHODS AND APPARATUS FOR CONVERTING OXYGENATE-CONTAINING FEEDSTOCKS TO GASOLINE AND DISTILLATES

摘要

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, 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.

1. A process for forming a refined hydrocarbon comprising:
(a) providing a first mixture comprising ≧10 wt % of at least one oxygenate, based on the weight of the first mixture; (b) 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; (c) 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, wherein the P2=P1±200 psi; and (d) recovering at least a portion of the gasoline boiling range components and distillate boiling range components.
