Publication number: 20210071204Abstract: A bioethanol production method using lignocellulosic biomass as a raw material, the method being adapted to increase the ethanol concentration of a fermentation liquid obtained in a fermentation step and reduce the distillation load without having to use specialized equipment in solubilizing the biomass by enzymatic hydrolysis of cellulose contained in the biomass. When a solid residue of the cellulosic biomass, from which hemicellulose has been removed, is mixed with an aqueous solution containing a cellulose-hydrolyzing enzyme in a reaction vessel, ethanol is added in an amount of 3 to 6% by mass. Bacterial proliferation is suppressed during hydrolysis of cellulose, and the ethanol concentration achieved in ethanol fermentation of a saccharified solution is increased, so that the distillation load is reduced. The ethanol added at the time of hydrolysis can be collected during distillation of the alcoholic fermentation liquid and reused.Type: ApplicationFiled: December 10, 2018Publication date: March 11, 2021Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Takashi NISHINO, Noriaki IZUMI, Hironori TAJIRI, Shoji TSUJITA, Asuka ODA, Manabu MASAMOTO, Yusuke WARATANI

Publication number: 20200332328Abstract: A saccharified solution production method in which cellulosic biomass is solubilized by enzymatic hydrolysis of cellulose contained in the cellulosic biomass, the method being adapted to quickly solubilize the biomass and give a slurry while keeping a high solids concentration in a reaction vessel. The biomass pulverized and an aqueous solution containing a cellulose-hydrolyzing enzyme are mixed in one reaction vessel including no baffle plate disposed in its interior, and the cellulosic biomass is solubilized under stirring. Afterwards, the contents of the reaction vessel are transferred to another reaction vessel including a baffle plate disposed in its interior, and enzymatic hydrolysis of cellulose is allowed to proceed. The solids concentration in the first reaction vessel is preferably 15 to 30% by mass. The efficiency of stirring during enzymatic hydrolysis of cellulose is enhanced, and thus the amount of sugar production can be increased.Type: ApplicationFiled: December 10, 2018Publication date: October 22, 2020Applicant: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Takashi NISHINO, Noriaki IZUMI, Hironori TAJIRI, Shoji TSUJITA, Asuka ODA, Manabu MASAMOTO, Yusuke WARATANI

Patent number: 10570432Abstract: A method for producing a saccharified solution making it possible that while the concentration of a solid in a reactor is kept high at an initial stage of hydrolyzing a cellulose contained in a biomass with an enzyme, the biomass is earlier solubilized to be made into a slurry form. In the method, at an initial stage of mixing an aqueous solution containing a biomass pulverized in a reactor, the aqueous solution is poured into reactor, and then pulverized biomass is supplied thereinto step by step while content in reactor is stirred. A final solid concentration in reactor is set into the range of 15 to 30% both inclusive by mass. The reactor's bottom plane is made into a conical or mirror plate form. At least in upper and lower parts of the reactor's inside, plural stirring fans having a long rotation radius are located to stir content in reactor.Type: GrantFiled: February 3, 2017Date of Patent: February 25, 2020Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Takashi Nishino, Noriaki Izumi, Hironori Tajiri, Hiromasa Kusuda, Shoji Tsujita, Manabu Masamoto

Patent number: 9481860Abstract: A method for removing bacterial contaminants from a saccharified solution capable of suppressing proliferation of bacterial contaminants in a fermentation tank without using an antibiotic in alcoholic fermentation of a biomass saccharified solution using normal yeast, and a fermentation system suited for conducting the method are provided. The method and system include drawing out a saccharified solution from a fermentation tank, conducting rough separation for recovering yeast from the solution, and conducting fine separation for removing bacterial contaminants from the solution, thereby removing only the contaminants while recovering yeast. The rough separation is through a filtering membrane having a pore size of 0.5 ?m or more and 5 ?m or less or centrifugal separation at 50G or higher and 500G or lower. The fine separation is through a filtering membrane having a pore size of 0.22 ?m or less, or centrifugal separation at 1000G or higher and 15000G or lower.Type: GrantFiled: December 3, 2013Date of Patent: November 1, 2016Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Noriaki Izumi, Manabu Masamoto, Satoshi Konishi
