Description
本発明者らは、上記の課題を解決するために鋭意検討した結果、糖化発酵工程から得られる残渣を、機械的処理して糖化発酵することで、工程全体に投入するエネルギーを削減でき、エタノール収率も向上することを見いだし、下記発明を完成した。
即ち、上記課題を解決するため、本発明は以下の(1)の方法を採用する。
(1)木質バイオマスを前処理した後、前処理をしたバイオマスを酵素糖化及びエタノール発酵する第一糖化発酵工程、第一糖化発酵工程より得られた糖化発酵液を液体と残渣に分離する固液分離工程、該固液分離工程から得られた残渣をアルカリ金属またはアルカリ土類金属の水酸化物、硫化物、炭酸塩または亜硫酸塩から選択された1種以上の薬品の水溶液に浸漬させてアルカリ処理するアルカリ処理工程、該アルカリ処理した残渣を磨砕処理する機械処理工程、該機械処理で得られた残渣を第一糖化発酵工程に返送することを特徴とする木質バイオマスからのエタノール製造方法。
As a result of intensive studies to solve the above-mentioned problems, the present inventors can reduce the energy input to the entire process by mechanically treating the residue obtained from the saccharification and fermentation process and performing saccharification and fermentation. The inventors found that the yield was improved and completed the following invention.
That is, in order to solve the above problems, the present invention employs the following method (1).
(1) After the woody biomass pretreated before first saccharification fermentation step process the biomass to enzymatic saccharification and ethanol fermentation, solid-liquid saccharification fermentation solution obtained from the first saccharification and fermentation process is separated into liquid and residue separation step, the solid-liquid hydroxides residue alkali metal or alkaline earth metal obtained from the separation step, sulfide, alkali is immersed in an aqueous solution of one or more drugs selected from carbonates or sulfites A method for producing ethanol from woody biomass, comprising: an alkali treatment step to be treated; a mechanical treatment step for grinding the alkali-treated residue ; and a residue obtained by the mechanical treatment being returned to the first saccharification and fermentation step .
次いで、濾過装置により固液分離を行い、液体分は、経路(ロ)を経由して減圧蒸留装置からなる蒸留分離工程に送られて生成アルコール留分と蒸留残渣留分とに分離され、生成アルコール留分は経路(ニ)を経由してアルコール貯槽に送られる。
Next, solid- liquid separation is performed by a filtration device, and the liquid component is sent to a distillation separation process consisting of a vacuum distillation device via a path (b) to be separated into a product alcohol fraction and a distillation residue fraction. The alcohol fraction is sent to the alcohol storage tank via the route (d).
