日本挥发油公司、三菱瓦斯化学公司和 Itochu公司已开发出一种用二甲醚 (DME)合成城市煤气的工艺。与使用石油液化气或石脑油的现存工艺相比，或与使用甲醇、目前仍在开发过程中的工艺相比较，新工艺更具经济性，因而它有希望作为替代天然气的新能源。作为一种对环境友好的物 Japan Volatile Oil Company, Mitsubishi Gas Chemical Company and Itochu Corporation have developed a process for the synthesis of city gas with dimethyl ether (DME). The new process is more economical than existing processes using liquefied petroleum gas or naphtha, or compared to processes that use methanol, which is still under development, so it is promising as a new alternative to natural gas. As an environmentally friendly thing
