Abstract

Characteristic of hydrogen production was investigated to find the optimum heat pretreatment conditions for the anaerobic fermentation of food waste. The heat pretreatment of food waste enhanced the hydrogen yield due to the increase of soluble chemical oxygen demand (SCOD) and carbohydrate content. This result revealed that the maximum degrees of disintegration of SCOD and carbohydrate content were 55.1% and 223.6%, respectively. On the other hand, the improvement of hydrogen yield was insignificantly affected by heating reaction time at longer than 20 min; the increase of hydrogen yield was only about 7% between 20min and 1 hour. Therefore, the increase of reaction time more than 20min was not necessary.

음식폐기물의 혐기성 발효시 열적 전처리의 최적 조건을 도출하기 위하여 수소 발생 특성을 평가하였다. 음식폐기물의 열적 전처리의 경우 용해성 화학적 산소요구량(SCOD)과 탄수화물 함량을 증가시켜 수소 수율을 향상시키는 것으로 나타났다. 실험결과 SCOD와 탄수화물을 기준으로 한 최대 가용화 효율은 각각 55.1%와 223.6%로 나타났다. 반응시간에 따라 전처리 효과는 증가하는 경향을 보였으나 20분간 1시간 비교시 약 7%의 차이를 보여 20분 이상의 반응시간의 증가는 크지 않은 것으로 나타났다.
