In this study, we investigated optimal reaction conditions for furfural production from lignocellulosic biomass by two-stage acid treatment. Furfural produced by this method was recovered using XAD-4 resin. Oxalic and sulfuric acid were used as catalysts for the first stage of treatment. The concent...

목질계 바이오매스의 특징은? | 2세대 바이오매스인 목질계 바이오매스는 자연계에 그 양이 풍부하고 재생가능하며 대기 중의 이산화탄소를 증가시키지 않는 탄소중립적인 특성을 가진 청정에너지원이다(Silva et al. 2009). | |
목질계 바이오매스의 세포벽은 어떤 물질로 구성되어 있는가? | 2009). 목질계 바이오매스의 세포벽은 주로 셀룰로오스, 헤미셀룰로오스, 리그닌으로 구성되어 있으며 유기적으로 연결되어 있어 이를 효율적으로 이용하기 위해서는 전처리 과정이 필요하다. 헤미셀룰로오스는 5탄당과 6탄당을 포함한 이종의 당으로 구성되어 있으며 자연계에 두 번째로 많이 존재한다. | |
푸르푸랄은 에탄올 발효에 어떤 영향을 미치는가? | 일반적으로 푸르푸랄은 에탄올 발효저해물질로 알려져 있다. 이것은 가수분해산물에 일정한 농도 이상을 포함하게 되면 에탄올 발효에 민감하게 영향을 준다(Delgenes et al. 1996). |
