Abstract

Torrefaction is a thermal treatment process to pre-treat biomass at temperature of $200{\sim}300^{\circ}C$ under an inert atmosphere. It was known that torrefaction process strongly depended on the decomposition temperature of the lignocellulosic constituents in biomass. In this work, the torrefaction characteristics of baggase has been studied. This study focuses on the relation between the energy yields, heating values, gas emission, volatile and ash constituents with torrefaction temperatures and times. The activation energies of baggase torrefaction has been studied by using TGA (Thermogravimetric Analyzer). From this work, it was seen that ash constituents and heating values were increased with torrefaction temperature, while volatile constituents and energy yields decreased. It was also found that carbon monoxide containing oxygen were decomposed at a lower temperature than those of hydrocarbon compounds, $C_xH_y$.

반탄화는 $200{\sim}300^{\circ}C$의 불활성분위기에서 바이오매스를 전처리하는 열처리공정이며 이러한 반탄화 공정은 바이오 매스에 함유된 섬유질성분의 분해온도에 크게 영향을 받은 것으로 알려져 있다. 본 연구에서는 사탕수수 부산물의 반탄화 특성에 관한 연구를 수행하였으며 반탄화 온도 및 반탄화 시간에 따른 에너지 수율, 발열량 및 발생가스 그리고 가연분과 회분의 관계에 중점을 두었다. 또한 본 연구에서는 TGA(Thermogravimetric Analyzer)를 이용한 사탕수수 부산물의 반탄화 반응에 대한 활성화 에너지의 변화도 함께 고찰하였다. 본 연구로부터 반탄화 온도에 따라 회분 및 발열량은 증가하였으나 가연분 및 에너지 수율은 감소하였으며 또한 산소성분을 함유한 일산화탄소가 탄화수소 화합물, $C_xH_y$ 보다 더 낮은 온도에서 분해되기 시작하는 것을 확인할 수 있었다.
