摘　　要：90年代发现二甲醚是可以替代柴油的超低污染燃料以及作为液化石油气的代用品;此外,它还可用于制备低碳烯烃。与此同时,将合成气一步转化为二甲醚的研究开发工作在国内外亦很活跃,可望显著降低装置投资及产品成本。本文评介了这两方面的进展情况。In 1990s,it was found that the dimethyl ether as a super-low pollution fuel can be used to replace diesel oil and liquefied petroleum gas,in addition,it also can be used to prepare light olefin.In the meantime,the research and development of converting synthesis gas in one step to dimethyl ether are brisk at home and abroad,so the installation investment and product cost may be markedly decreased.This paper appraises the development situation in these two aspects.
