    • 본 발명은 목질계 바이오매스로부터 바이오에탄올을 제조하는 방법에 관한 것으로서, 본 발명의 방법은 전처리 전에 바이오매스를 온수로 추출하여 무기염류 등 추출성 물질을 제거함으로써 효소 당화 원료의 불순물 함량을 최소화할 수 있고, 온수 추출성 물질을 제거한 바이오매스를 자일란 수율이 최대가 되는 조건에서 전처리함으로써 당 과분해산물의 생성을 최대한 억제하고, 이후 고액분리로 얻은 전처리 고형분을 물로 세척하지 않고 효소당화한 후 얻어진 당용액의 분리막을 이용한 농축만으로도 발효당을 저렴하게 제조할 수 있고, 이로부터 높은 수율로 바이오에탄올을 제조할 수 있다.
    • 本发明涉及一种从木质生物质生产生物乙醇的方法。 根据该方法,在预处理前用热水提取生物质,以除去无机盐等可萃取物质。 因此,可以使酶水解材料的杂质含量最小化。 此外,通过在最大化木聚糖产率的条件下,通过预热由热水除去可提取物质的生物质,尽可能地抑制过度分解的糖产物的产生。 随后,通过仅用浓缩通过酶固化获得的预固化固体含量通过固液分离获得的糖溶液,而不用水洗涤固体含量,可以以低成本生产可发酵糖。 因此,可以高产率生产生物乙醇。
