Bio Oil Conversion

Biomass Conversion & Upgrading

현재 전 세계가 당면한 과도한 화석연료 (석탄, 석유) 사용으로 인한 온실가스 발생으로 재생가능하며 지속가능한 에너지원으로부터 발전용 및 수송용 연료를 제조하기 위한 공정을 개발하는 것은 매우 중요합니다. 바이오매스 (나무, 거대조류, 미세조류, 하수슬러지 등)는 지구상에 존재하는 매우 풍부한 재생가능한 자원이며 탄소중립적인 에너지원입니다. GEMP@SKKU에서는 재생가능한 바이오매스로부터 발전용 바이오연료 및 수송용 바이오연료 (가솔린, 디젤, 항공유)를 제조할 수 있는 바이오매스 전환 및 업그래이딩 공정을 연구중에 있습니다. Extensive efforts are being made to develop renewable and sustainable energy sources, and cost-effective energy processes, owing to concerns regarding global warming and fossil fuel depletion. Biomass is considered as one of the most promising renewable energy resources as it is carbon neutral and abundant. GEMP @ SKKU focuses on developing new green chemical process to produce clean and renewable biogasoline, biodjetful and biodiesel.
