Methods Of Spraying Saccharification Enzymes And Fermentation Organisms Onto Lignocellulosic Biomass For Hydrolysis And Fermentation Processes

View page
US Patent:
8389243, Mar 5, 2013
Filed:
Jun 16, 2010
Appl. No.:
12/816999
Inventors:
Johnway Gao - Federal Way WA, US
Benjamin Levie - Mercer Island WA, US
Dwight Anderson - Puyallup WA, US
Assignee:
Catchlight Energy LLC - Federal Way WA
International Classification:
C12P 19/00
C12P 1/02
US Classification:
435 72, 435162, 435163, 435164, 435165, 435170, 435171, 435209
Abstract:
The present invention provides spray methods of delivering saccharification enzymes, fermentation organisms, and other hydrolysis or fermentation ingredients onto lignocellulosic biomass. The methods reduce the need for mechanical mixing when the biomass solids are undergoing enzymatic hydrolysis, and reduce dilution to allow higher product titers in the hydrolysis and/or fermentation steps.

Methods For Producing A Hydrolysate And Ethanol From Lignocellulosic Materials

US Patent:
20080227161, Sep 18, 2008
Filed:
Mar 17, 2008
Appl. No.:
12/050113
Inventors:
Benjamin E. Levie - Mercer Island WA, US
Amar N. Neogi - Kenmore WA, US
Sheldon J B Duff - Richmond, CA
Jeffrey E. Mayovsky - Puyallup WA, US
Dwight E. Anderson - Puyallup WA, US
Robert C. Eckert - Auburn WA, US
Chundakkadu Krishna - Federal Way WA, US
Assignee:
WEYERHAEUSER COMPANY - Federal Way WA
International Classification:
C12P 19/22
C12P 19/00
C12P 7/10
US Classification:
435 95, 435 72, 435165
Abstract:
A method for producing a hydrolysate from lignocellulosic materials generally includes fiberizing the lignocellulosic materials, separating the lignocellulosic materials into at least a first portion and a second portion, wherein at least the first portion includes lignin, treating the first portion to deactivate at least a portion of the lignin in the first portion, re-combining the first and second portions after treating the first portion, and hydrolyzing the lignocellulosic materials with enzymes to produce a hydrolysate.

Pretreatment Of Ligno-Cellulosic Biomass With Sulfonation

View page
US Patent:
20110124056, May 26, 2011
Filed:
Sep 29, 2010
Appl. No.:
12/894042
Inventors:
Benjamin Levie - Mercer Island WA, US
Rajesh Gupta - Katy TX, US
Johnway Gao - Federal Way WA, US
Dwight Anderson - Puyallup WA, US
Assignee:
CHEVRON U.S.A. INC. - San Ramon CA
International Classification:
C12P 19/04
C12P 19/02
C13K 1/02
US Classification:
435101, 435105, 127 37
Abstract:
Provided are methods for the pretreatment of ligno-cellulosic biomass such as softwoods with bisulfite such as ammonium bisulfite without the need for exogenous acid. In one variation, a method of pretreating ligno-cellulosic biomass is provided including the following steps: a) providing ligno-cellulosic biomass; b) contacting the ligno-cellulosic biomass with a solution comprising bisulfite at an amount between 1 and 10% of a dry weight of the ligno-cellulosic biomass to form a slurry; c) heating the slurry to a first temperature of 150-210 C. for a first period of time to form a first mixture; d) cooling the first mixture to a second temperature of 100-200 C. to form a second mixture; and e) maintaining the second mixture at the second temperature for a second period of time to form pretreated ligno-cellulosic biomass; wherein the first temperature is higher than the second temperature.

Methods Of Enabling Enzymatic Hydrolysis And Fermentation Of Lignocellulosic Biomass With Pretreated Feedstock Following High Solids Storage In The Presence Of Enzymes

View page
US Patent:
20120264178, Oct 18, 2012
Filed:
Mar 9, 2012
Appl. No.:
13/416911
Inventors:
Dwight ANDERSON - Puyallup WA, US
Johnway Gao - Federal Way WA, US
Benjamin Levie - Mercer Island WA, US
International Classification:
C12P 19/02
C12P 19/00
US Classification:
435105, 435 72
Abstract:
The present invention provides methods of producing pretreated lignocellulosic biomass combined with enzymes for the storage and transporation of the pretreated lignocellulosic biomass that may be used in biofuel and bioproduct production. The methods allows the coexistence of the pretreated lignocellulosic biomass and the enzymes during storage and transporation, the immediate hydrolysis of the pretreated lignocellulosic biomass to produce sugars, without further addition of enzymes, in a biofuel or bioproduct production site, the enhancement of the final hydrolytic activity of the pretreated lignocellulosic biomass, and/or the reduction in sensitivity of the inhibitors in the pretreated lignocellulosic biomass.

Solid Lignocellulosic Hydrolysate And Methods To Prepare A Solid Lignocellulosic Hydrolysate

View page
US Patent:
20130118483, May 16, 2013
Filed:
Nov 11, 2011
Appl. No.:
13/294867
Inventors:
Johnway Gao - Federal Way WA, US
Dwight Anderson - Puyallup WA, US
Benjamin Levie - Mercer Island WA, US
International Classification:
C13B 50/00
C13K 1/02
US Classification:
127 30, 127 37
Abstract:
The present disclosure provides a solid lignocellulosic hydrolysate and methods to prepare the solid lignocellulosic hydrolysate from a woody biomass or an herbaceous biomass. The solid lignocellulosic hydrolysate may be used in the production of biofuels, bioproducts, and food products. The solid lignocellulosic hydrolysate allows for ease of storage, ease of transportation and handling of the solid lignocellulosic hydrolysate, and ease of use in biological or fermentation processes or chemical processes for the production of biofuel, bioproducts, chemicals and food products due to the bulk handling characteristics (e.g., solubility and rate of dissolution) of the solid lignocellulosic hydrolysate.

Pulp Chip Fissure Test Device And Method For Estimating Screened Pulp Yield

View page
US Patent:
59707836, Oct 26, 1999
Filed:
Feb 20, 1999
Appl. No.:
9/253168
Inventors:
Benjamin E. Levie - Mercer Island WA
Gail E. Johnson - Auburn WA
Gevan R. Marrs - Puyallup WA
Assignee:
Weyerhaeuser Company - Tacoma WA
International Classification:
G01N 502
US Classification:
73 73
Abstract:
The invention consists of a method and apparatus for estimating screened pulp yield using water uptake rate of a sample of screened pulp chips. A dried chip sample is placed in a wire basket and totally immersed in water. A balance records the rate of water uptake over a period of about 35 seconds. This is preferably entered directly into a computer to give an output closely predicting the yield of screened pulp.
