Abstract

Increasing of energy demand due to the rapid growth of global population and the development of world economy has inevitably resulted in the continuously increase of fossil fuel usage in the world. However, highly dependence on fossil fuels has necessarily brought about critical environmental issues and challenges such as severe air pollutions and rapid global warming. In order to settle these environmental and energy problems, clean energy generations in the conventional combustion processes have widely adapted in the world. In particular, novel thermochemical conversion processes such as pyrolysis and gasification have rapidly been applied for generating clean energy. Fluidized bed technologies having advantages such as various fuel use, easy continuous operation, high heat and material transfer, isothermal operation, and lower operation temperature are widely adopted and used because they are suitable for thermochemical energy conversion. The latest research trends and important findings in the thermo-chemical conversion process with fluidized bed technologies are summarized in this review. Also, the need for research such as layered materials and substances to reduce fine dust (biomass, natural resource waste, etc.) was suggested. Through this, it is intended to increase interest and understanding in fluidized bed technology and to present directions for solving future challenges in fluidized bed process technology development.

지속적인 인구의 증가와 경제의 발전으로 인한 전세계 에너지 수요의 증가는 화석연료의 이용을 끊임없이 증가시키고 있다. 그러나 화석연료에 대한 높은 의존도는 환경오염과 급격한 지구온난화라는 새로운 문제를 야기시켰다. 이의 해결을 위해 전통적인 연소에서 벗어나 열분해, 가스화와 같은 새로운 열화학적 전환 공정을 이용한 청정 에너지 생산이 빠르게 확산되고 있다. 특히 다양한 연료의 이용, 쉬운 연속조업, 높은 열 및 물질전달, 등온 조업, 낮은 조업 온도 등의 특성들을 가지는 유동층 공정은 열화학적 에너지 전환에 적합하기 때문에 널리 채택되어 이용되고 있다. 이에 본 총설에서는 열분해, 가스화, 연소에 적용된 최근의 유동층 공정 연구의 중요한 결과들을 정리하였다. 더불어 유동층 열화학적 공정에서 주로 연구되지 않은 층물질, 미세먼지 저감을 위한 물질(바이오매스, 천연 자원 폐기물 등)과 같은 연구의 필요성을 제시하였다. 이를 통해 유동층 기술에 대한 관심과 이해를 높이고, 유동층 공정 기술 개발의 미래 과제를 해결하기 위한 방향을 제시하고자 한다.
