二甲醚是一种清洁燃料,可用于交通燃料和民用燃气。“十一五”以来,我国二甲醚产能增长迅速,2013年达到1348万吨,10万吨以上规模企业64家。在产能迅速增长的同时,国家和地方也相继出台了鼓励发展政策,颁布了相关标准,开展了科技攻关项目。但由于标准体系不健全,缺乏相关的专用器具,二甲醚市场应用受到极大限制,相关企业开工率严重不足,2013年二甲醚总产量约449万吨,开工率仅为三分之一。自上世纪90年代开始,我国就开展了二甲醚发动机及
Dimethyl ether is a clean fuel that can be used in transportation fuels and civil gas. Since the “Eleventh Five-Year”, China’s dimethyl ether production capacity has grown rapidly in 2013 reached 13.48 million tons, more than 100,000 tons of 64 large-scale enterprises. In addition to the rapid growth of production capacity, the state and local governments have also successively promulgated policies to encourage development, promulgated relevant standards and conducted scientific and technological research projects. However, due to the imperfect standard system and the lack of related special equipment, the market application of dimethyl ether has been greatly restricted. The operating rate of related enterprises is seriously insufficient. In 2013, the total output of DME was 4.49 million tons, and the operating rate was only one third . Since the 90s of last century, China has launched a dimethyl ether engine and
