사탕수수 부산물의 반탄화 특성에 관한 연구 = A Study on Torrefaction Characteristics of Baggase

다국어 초록 (Multilingual Abstract)

Torrefaction is a thermal treatment process to pre-treat biomass at temperature of 200~300 oC under aninert atmosphere. It was known that torrefaction process strongly depended on the decomposition temperature of the lignocellulosicconstituents in biomass. In this work, the torrefaction characteristics of baggase has been studied. This studyfocuses on the relation between the energy yields, heating values, gas emission, volatile and ash constituents with torrefactiontemperatures and times. The activation energies of baggase torrefaction has been studied by using TGA (ThermogravimetricAnalyzer). From this work, it was seen that ash constituents and heating values were increased withtorrefaction temperature, while volatile constituents and energy yields decreased. It was also found that carbon monoxidecontaining oxygen were decomposed at a lower temperature than those of hydrocarbon compounds, CxHy.
