Appl. No.:

13/117930

Inventors:

Rajeswar Gattupalli - Arlington Heights IL, US
Stephen W. Sohn - Arlington Heights IL, US
Michael J. Cleveland - Northbrook IL, US

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C07C 7/12
B01D 11/04
C07C 7/13

US Classification:

585821, 585820, 422256

Abstract:

Processes and apparatuses are provided for producing a normal paraffin product or a substantially linear paraffin product from a feed including normal hydrocarbons, non-normal hydrocarbons, and contaminants. The contaminants are extracted from the feed through contact with an ionic liquid stream to form a clean stream of hydrocarbons. The desired hydrocarbons are selectively adsorbed from the clean stream of hydrocarbons with a molecular sieve to remove the desired hydrocarbons from the non-desired hydrocarbons. A desorbent recovers the desired hydrocarbons from the molecular sieve. Then the desired hydrocarbons are separated from the desorbent to yield the normal paraffin product.

Abstract:

Methods for producing light olefins are provided. An exemplary method includes providing an oxygenate compound capable of converting to light olefins in a catalytic reaction or to a clean reaction intermediate compound of the catalytic reaction and converting the oxygenate compound to the clean reaction intermediate compound in a chemical reaction. The chemical reaction produces a gas-phase product comprising the clean reaction intermediate compound, unconverted oxygenate, and a reaction byproduct. The method further includes cooling the gas-phase product to condense unconverted oxygenate and reaction byproduct while maintaining the clean reaction intermediate compound in a gas phase and separating the clean reaction intermediate compound, the unconverted oxygenate, and the reaction byproduct into a first stream including the clean reaction intermediate compound and a second stream including the unconverted oxygenate and the reaction byproduct. Still further, the method includes contacting the first stream with a catalyst configured for producing light olefins.
