Abstract

Fuels based on petroleum will eventually run out in the near future. DME (Di-methyl Ether) is a clean energy source that can be manufactured from various raw materials such as natural gas, coal as well as biomass. As DME has no carbon-carbon bond in its molecular structure and is an oxygenate fuel, its combustion essentially generates no soot as well as no SOx. Because the physical properties of DME are similar to those of LPG, the LPG distribution infrastructure can be converted to use with DME. DME has such high cetane number of 55~60 that it can be used as a diesel engine fuel. Practical use of DME as a next-generation clean fuel or next-generation chemical feedstock is advancing in the fields of power generation, diesel engines, household use, and fuel cells, among others. The purpose of this paper is review the characteristics, standardization, status of research and development in domestic and foreign countries of DME.

석유를 기반으로 한 연료는 가까운 미래에 고갈될 것이다. 디메틸에테르(Di-methyl Ether, DME)는 청정에너지이며 천연가스,석탄 및 바이오매스 등으로 생산이 가능하다.DME는 분자구조 내에 탄소-탄소 결합이 없는 함산소 연료로 연소시 그을음과 황산화물을 발생하지 않으며, 물리적 특성이 액화석유가스(Liquified Petroleum Gas, LPG)와 매우 유사하여 LPG 유통인프라를 그대로 활용할 수 있다. DME는 세탄값이 55~60 정도로 높아 디젤 자동차용 연료로도 활용이 가능하다.차세대 청정연료로 혹은 차세대 화학공업 원료물질로 전력생산,디젤 연료, 가정용 연료 및 연료전지 등에 사용이 가능하다.본 총설에서는DME의 특성, 표준화, 국내외의 기술개발현황, 대체연료로서의 활용에 대해 살펴보고자 한다.
