Patent number: 10227623Abstract: A process for mechanical destructuring of cellulosic biomass was developed that makes use of a short application of high compression, impact, and shearing forces. The biomass may be destructured using a specific energy input that is less than 40% of the total combustible energy of the biomass. The destructured biomass, with or without saccharification and/or in-feed glycosyl hydrolase enzymes, may be used in feed applications.Type: GrantFiled: November 18, 2014Date of Patent: March 12, 2019Assignee: E I DU PONT DE NEMOURS AND COMPANYInventors: Wathudura Indika Namal De Silva, Paul Joseph Fagan, F Glenn Gallagher, Zheng-Zheng Huang, Guangliang Gary Liu, Aaron Perelman, Luis Fernando Romero Millan, Anton Shpilsky, Daniel A Slanac, Maria Walsh

Publication number: 20150147786Abstract: A process for mechanical destructuring of starch-based biomass was developed that makes use of a short application of high compression, impact, and shearing forces. The biomass may be destructured using a specific energy input that is less than 40% of the total combustible energy of the biomass. The destructured starch-based biomass, with or without saccharification and/or in-feed glycosyl hydrolase enzymes, may be used in feed applications. The destructured starch-based may saccharified to produce syrups and fermentable sugars, and for production of products including ethanol using a biocatalyst.Type: ApplicationFiled: November 18, 2014Publication date: May 28, 2015Inventors: KATHLEEN A CLARKSON, F Glenn Gallagher, Aaron Perelman, Luis Fernando Romero Millan, Vivek Sharma, Jayarama K.

Publication number: 20140131189Abstract: A combined tangential shear homogenizing and flashing apparatus for destructuring pretreated biomass comprises a housing connectable to a source of pressurized pretreated biomass, and a stator and a rotor mounted within the housing. The stator and rotor being confrontationally disposed and spaced apart by an axial gap. The gap as a radially outer region having a uniform dimension and a radially inner region having at least one section exhibiting a non-uniform dimension. The radially outer region defines a valve. In use, rotational movement of the rotor with respect to the stator imparts a tangential shear to a volume of pretreated biomass. The tangential shear homogenizes the biomass while a pressure difference causes a partial phase separation of the homogenized biomass into vapor and liquid phases such that the pretreated biomass undergoes at least a three-fold total volumetric increase and a weight transition to a vapor of at least one percent.Type: ApplicationFiled: March 8, 2013Publication date: May 15, 2014Applicant: E I DU PONT DE NEMOURS AND COMPANYInventor: F.

Publication number: 20140131492Abstract: A combined tangential shear homogenizing and flashing apparatus for destructuring pretreated biomass comprises a housing connectable to a source of pressurized pretreated biomass, and a stator and a rotor mounted within the housing. The stator and rotor being confrontationally disposed and spaced apart by a predetermined uniformly dimensioned axial gap. In use, rotational movement of the rotor with respect to the stator imparts a tangential shear to a volume of pretreated biomass. The tangential shear homogenizes the volume of pretreated biomass while a pressure difference causes a partial phase separation of the homogenized biomass into vapor and liquid phases such that the pretreated biomass undergoes at least a three-fold total volumetric increase and a weight transition to a vapor of at least one percent (1%).Type: ApplicationFiled: March 8, 2013Publication date: May 15, 2014Applicant: E I DU PONT DE NEMOURS AND COMPANYInventor: F Glenn Gallagher

Publication number: 20140131487Abstract: A system for destructuring pretreated biomass includes a pretreating device for producing a pressurized mass of material having a predetermined elevated temperature a process utility disposed downstream of the pretreating device; and a combined tangential shear homogenizing and flashing apparatus connected intermediate the pretreating device and the process utility. The combined tangential shear homogenizing and flashing apparatus imparts a tangential shear to a volume of pretreated biomass while a pressure difference causes a partial phase separation of the homogenized biomass into vapor and liquid phases. A conduit for providing uninterrupted fluid communication between the outlet of the housing and the process utility for conducting the vapor and liquid phases directly into the process utility.Type: ApplicationFiled: March 8, 2013Publication date: May 15, 2014Applicant: E I DU PONT DE NEMOURS AND COMPANYInventor: F.

Publication number: 20140131490Abstract: A combined tangential shear homogenizing and flashing apparatus for destructuring pretreated biomass comprises a housing connectable to a source of pressurized pretreated biomass, and a stator and a rotor mounted within the housing. The stator and rotor being confrontationally disposed and spaced apart by a non-uniformly dimensioned axial gap. The least axial dimension between the rotor and the stator defining a restriction to a biomass flow. In use, rotational movement of the rotor with respect to the stator imparts a tangential shear to a volume of pretreated biomass. The tangential shear homogenizes the volume of pretreated biomass while a pressure difference causes a partial phase separation of the homogenized biomass into vapor and liquid phases such that the pretreated biomass undergoes at least a three-fold total volumetric increase and a weight transition to a vapor of at least one percent (1%).Type: ApplicationFiled: March 8, 2013Publication date: May 15, 2014Applicant: E I DU PONT DE NEMOURS AND COMPANYInventor: F Glenn Gallagher

Publication number: 20130269526Abstract: Described are methods and apparatus for the selective removal of CO2 from a mixture of gases. The method comprises contacting a first gaseous mixture containing CO2 in an absorber with an absorbent having substantial selectivity for CO2, thereby forming a second mixture of absorbed CO2 and absorbent. After separating any nonabsorbed gases from the second mixture of CO2 and absorbent, the second mixture enters a separator wherein the CO2 is released from the absorbent. The absorbent is recycled back to the absorber to start the process over. The released CO2, is then compressed in one or more stages. Each stage provides a compression step to heat the released CO2, followed by a cooling step. The heat generated during the cooling of the CO2 is captured by intercoolers and recycled to operate the capture and separating process in a substantial manner, if not entirely.Type: ApplicationFiled: September 12, 2012Publication date: October 17, 2013Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: STEVEN RAYMOND LUSTIG, F.
