摘要
综述了二甲醚的性质、用途、生产技术 ,分析了用煤或天然气合成二甲醚的经济性 ,展望了二甲醚作为清洁燃料的发展前景。结论认为 :一步法合成二甲醚具有较高的经济价值 ,CO2 加氢直接制二甲醚具有很强的理论与战略意义 ,实现二甲醚代替柴油需要政府推动与市场驱动相结合。
The properties, application and production technology of dimethyl ether (DME) were described. The economic evaluation of production technology of DME from CNG or coal was analyzed. The development prospect of DME, using as a clean fuel, was also reviewed. It was pointed out that one step synthesis of DME had best economic efficiency, and the hydrogenation of CO 2 had important value in theory and strategy; to realize the replacement of diesel oil by DMW needed combination of government promoting and market driving.
