Patent number: 9222044Abstract: Methods for producing low oxygen biomass-derived pyrolysis oil are provided. Starting biomass-derived pyrolysis oil is deoxygenated by exposing the biomass-derived oil to a first catalyst in the presence of hydrogen-containing gas at first hydroprocessing conditions to produce a partially deoxygenated biomass-derived pyrolysis oil. The first catalyst has a neutral catalyst support. The partially deoxygenated biomass-derived pyrolysis oil is exposed to a second catalyst in the presence of additional hydrogen-containing gas at second hydroprocessing conditions to produce a hydrocarbon product. The biomass-derived pyrolysis oil may be esterified prior to deoxygenation. A portion of the low oxygen biomass-derived pyrolysis oil is recycled.Type: GrantFiled: July 26, 2010Date of Patent: December 29, 2015Assignee: UOP LLCInventors: Thomas Traynor, Timothy A. Brandvold

Patent number: 8864999Abstract: Methods for regenerating acidic ion-exchange resins and reusing regenerants in such methods are provided. A spent ion-exchange resin is contacted with an alcohol ion-exchange regenerant. The spent ion-exchange resin is thereafter contacted with an acidic ion-exchange regenerant to recharge the acidic ion-exchange resin to produce a regenerated acidic ion-exchange resin. Metal- and water-containing biomass-derived pyrolysis oil is then contacted with the regenerated acidic ion-exchange resin to produce low metal, water-containing biomass-derived pyrolysis oil. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.Type: GrantFiled: December 23, 2009Date of Patent: October 21, 2014Assignee: UOP LLCInventors: Timothy A.

Patent number: 8524087Abstract: Low metal, low water biomass-derived pyrolysis oils and methods for producing the same are provided. Metal- and water-containing biomass-derived pyrolysis oil is contacted with an acidic ion-exchange resin having sulfonic acid groups to produce a low metal, water-containing biomass-derived pyrolysis oil. The low metal, water-containing biomass-derived pyrolysis oil is removed from the spent ion-exchange resin after ion-exchange. The low metal, water-containing biomass-derived pyrolysis oil is distilled to produce a low metal, low water biomass-derived pyrolysis oil and a distillation product. The distillation product comprises one or both of an alcohol ion-exchange regenerant and an acidic ion-exchange regenerant which may be used to regenerate the spent ion-exchange resin. The regenerated acidic ion-exchange resin may be recycled. The spent alcohol and acid ion-exchange regenerants may be recovered and recycled.Type: GrantFiled: December 23, 2009Date of Patent: September 3, 2013Assignee: UOP LLCInventors: Stanley J.

Patent number: 7969644Abstract: A method and system for reducing speckle in an image produced from a coherent source of radiation is provided. The method includes coupling a source beam received from a coherent optical source into an optical fiber. A position of at least a portion of the fiber may be modulated using a ditherer.

In accordance with a particular embodiment, the source beam may be projected from the microlens diffuser onto a spatial modulator. The spatial modulator may be positioned to project the source beam via an imaging lens, to a target.Type: GrantFiled: December 17, 2008Date of Patent: June 28, 2011Assignee: Elbit Systems of America, LLCInventors: Michael M.
