Abstract: PURPOSE: Provided is a method for fermenting paper slurry using a helical ribbon agitator to increase the productivity of alcohol. CONSTITUTION: The method for fermenting paper slurry is characterized by the following steps of: i) obtaining dissociated paper which contains 57% cellulose by adding used paper and 2L of distilled water into a disintegrator and centrifuging the paper at 1000rpm for 15 minutes; ii) adding the dissociated paper, medium containing 2% of corn steep liquor, 30FPU/g of cellulase, and 13.3 IU/g of beta-glucosidase to citrate buffer of pH 4.8 during an early stage of fermentation intermittently; and iii) agitating the mixture by a helical ribbon agitator.

Abstract: PURPOSE: An apparatus and method for pretreating high efficiency biomass using ammonia water capable of separating hemicellulose and lignin for the manufacture of ethanol through enzyme hydrolysis from cellulose(wood) based biomass are provided. Thereby, processing cost is reduced because the washing process of pretreated biomass is unnecessary and ammonia is inexpensive and reused. CONSTITUTION: In a pretreatment method of biomass for the manufacture of ethanol for fuel from cellulose(wood) based biomass, this pretreatment method comprises the steps of introducing cellulose based biomass into an elution reactor(2); supplying ammonia water to the elution reactor in such a manner that a retention time of ammonia water in the inner part of the elution reactor is about 10 to 30min; separating ammonia and lignin by vaporizing ammonia water in an ammonia reheater/lignin separator(8); and collecting ammonia in a collector(9), recycling ammonia, removing impurities and hydrolyzing.
Abstract translation: 目的:提供一种使用能够通过纤维素(木材)生物质的酶水解从而分离半纤维素和木质素用于制造乙醇的氨水预处理高效生物质的装置和方法。 因此,由于预处理的生物质的洗涤过程是不必要的,并且氨是廉价的并且被再利用,所以加工成本降低。 构成:在用于从基于纤维素(木材)的生物质制造燃料的乙醇的生物质的预处理方法中,该预处理方法包括将基于纤维素的生物质引入洗脱反应器(2)的步骤; 以洗脱反应器内部的氨水的停留时间为10〜30min左右的方式向洗脱反应器供给氨水; 通过在氨再热器/木质素分离器(8)中蒸发氨水分离氨和木质素; 并在收集器(9)中收集氨,回收氨,除去杂质并水解。
