摘　　要：介绍了二甲醚(DME)的生产方法及技术进展情况,并对其工艺特点进行了分析比较。以甲醇为原料的二甲醚生产技术较为成熟,该工艺流程较长,设备投资大,产品成本高,受甲醇市场波动的影响大。合成气法二甲醚的生产成本低,可以替代LPG及柴油成为新型燃料,对我国能源的优化利用具有重要意义。The production processes and technological progress of dimethyl ether and their process features are analyzed and compared. The dimethyl ether production technology by taking methanol as feedstock is maturer. The process has longer process flow, high equipment investment, high product cost and great variation influenced by methanol market. The production of dimethyl ether with synthesis gas process has a low production cost and can replace LPG and diesel oil and has become a new type fuel and this has an important significance for the optimized utilization of the energy of our country.
