二甲醚（DME）是一种清洁、可持续的替代燃料，可以通过合成气从天然气、煤炭或其他有机资源中生产。二甲醚的性能适用于生产发电燃料、交通运输燃料、家用燃料和化工产品。从偏远地区未利用的天然气或煤炭资源中生产二甲醚燃料将有助于解决能源-环境困境。在一个实验装置上（50公斤/天），开发了一种从合成气在泥浆床上直接合成二甲醚的创新工艺。在政府的支持下，1997年开始使用一个中试规模的工厂（每天5吨）进一步发展该项目。日本国际开发工程学会的可行性研究表明，二甲醚的生产成本与常规燃料价格相比具有竞争力，使用二甲醚发电的成本与燃煤电站相当，而且环境负荷要低得多。21世纪初，亚洲引进二甲醚燃料最现实的情况是，在日本作为火力发电厂燃料推广，在亚洲大城市作为清洁汽车燃料推广，在亚洲作为液化石油气或煤油的替代品推广。(C) 2000 Elsevier Science Ltd.版权所有。
Dimethyl ether (DME) is a clean and sustainable alternative fuel that can be produced from natural gas, coal or other organic resources through syngas. The properties of DME are suitable for the production of power generation fuel, transportation fuel, home fuel and chemicals. Production of DME fuel from unutilized natural gas or coal resources in remote areas will contribute in solving the energy-environment dilemma. An innovative process of direct synthesis of DME from syngas in a slurry bed has been developed with a bench plant (50 kg/day). Further development of the project using a pilot scale plant (5 t/day) commenced in 1997 with governmental support. The feasibility study of the International Development Engineering Society of Japan indicates that the production cost of DME is competitive to conventional fuel price, and the cost of electricity generation using DME is the same as that of a coal-fired power station with a much lower environmental load. The most realistic scenario for the introduction of DME fuel in Asia in the early 21st century is its promotion as a thermal power plant fuel in Japan as a clean motor vehicle fuel in large cities of Asia, and as a substitute for liquefied petroleum gas or kerosene in Asia.
