있는 biomass 자원화 기술 중의 하나가 fastpyrolysis 공정이다.
본 연구에서는 다양한 종류의 biomass 원료 중에서도 특히, 볏짚을 이용한 fastpyrolysis 공정을 도입하여, 반응 온도를 다양하게 변화시킴으로써 얻어지는 생성물간의 수율 변화 및 생성물 중 하나인 bio-gas의 특성에 대하여 알아보도록 한다.
pyrolysis. In this study, we applied fastpyrolysis technique, one of pyrolysis methods, to convert woody biomass under various reaction temperatures. As products, we could obtain char, oil and gas. Higher reaction temperature favored for the production of gas and around 500℃, the production of bio-oil was optimized. When smaller size feed applied, more oil and less char was obtained. Gas analy

1. 자연생태계와 농업생태계(관행농업생태계, 유기농업생태계)의 차이에 대하여 설명하시오. (20점)
1) 자연생태계
자연 생태계는 매우 복잡한 구조로 연결돼 있다. 다양한 생물과 무생물로 구성되어 있으며, 이들 간의 상호 작용도 복잡하다. 예를 들어 육지와 수상 생태계를 비교할 때, 필요한 먹이
