Literature review
- Necessity of torrefaction
Biomass의 특성상 1. 빠른 수분 흡수, 2. 미생물에 쉽게 오염, 3. 적은 발열량, 4. 분쇄가 잘 되지 않아 석탄과 함께 쓰지 못함.

- Treatment process
무산소 환경에서 200~300도 열처리하여 비결정성탄소를 생성시킴

- Product
Torrefied biomass 생성됨. 주 성분은 lignin + cellulose + hemicellulose

- Characteristic
질량이 약 40% 감소 Pentananunt et al. (1990), Medic et al.(2012)
수분이 빠지고 점화하기 쉬워짐 Weih-Hsin et al. (2011)
Torrefection 온도가 증가함에 따라 ash 성분 증가함. Anukam et al.(0000)
Torrefied biomass을 이용하면 gasification process 효율이 개선됨. Xue et al. 2014)
