摘要： A method for producing a concentrated saccharified solution using lignocellulosic biomass as a source material. The method includes filtering a saccharified solution obtained by hydrolysis of cellulosic biomass through a membrane separator having a separation membrane having a molecular cutoff ranging from 1000 or more and 7000 or less, and feeding it to a reverse osmosis membrane device to concentrate the same. By such treatment, the saccharides having small molecular weights contained in the saccharified solution are transferred to the filtrate, and the lignin and its decomposition product having large molecular weights are drained as a concentrated solution from the membrane separator. Accordingly, it is possible to prevent loss of saccharides contained in the saccharified solution, and to easily prevent occurrence of fouling in the reverse osmosis membrane used in concentration of the saccharified solution.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method of producing a saccharified solution, in which saccharified slurry is obtained by hydrothermally treating cellulosic biomass slurry in a supercritical state or a subcritical state by a continuous reactor. The method reduces the risk of a pressure reducing valve becoming clogged when the high-temperature and high-pressure slurry is flash-evaporated after being hydrothermally treated. Also provides an apparatus for producing a saccharified solution and a continuous reactor. At the time of hydrothermally treating the cellulosic biomass slurry by the continuous reactor continuously, the slurry is intensely stirred in a front part of the continuous reactor, and stirred in a rear part of the continuous reactor by a stirring device with low propelling force, such that the plug flow in the axial direction is kept while the slurry is being uniformly mixed with respect to the cross section perpendicular to the mixing axis.
