Abstract

본 연구는 거대 녹조류인 창자파래(Enteromorpha intestinalis)를 대상으로 고체 산촉매를 사용하여 환원당을 생산하고자 하였다. 가수분해 반응은 고액비, 촉매량, 반응온도와 반응시간을 대상으로 최적화하였다. 결과적으로 액/고비 7.5, 반응온도 140 oC, 촉매량 15%, 그리고 반응시간 2 hr에서 7.74 g/L의 환원당을 얻었다. 반면에 단지 0.13 g/L의 5-HMF만이 생성되었다. 이로부터 고체 산촉매를 이용한 해양 바이오매스 자원의 가능성을 확인하였다.

In this study, the hydrolysis of green macro-algae Enteromorpha intestinalis using solid acid catalyst was conducted to obtain total reducing sugar. The hydrolysis was optimized with four reaction parameters of liquid-to-solid (L/S) ratio, catalyst amount, reaction temperature, and reaction time. As a optimized result, the highest TRS of 7.74 g/L was obtained under condition of 7.5 L/S ratio, 140 oC, 15% catalyst amount and 2 hr. By the way, at this condition, only 0.13 g/L 5-HMF was detected. The solid acid-catalyzed hydrolysis of marine resources had the potential in the field of bioenergy.
