二甲醚经济:解决中国能源与环境问题的重大关键

中国的资源环境与人口增长、经济发展之间的矛盾 ,在 2 1世纪的前 30年内 ,将是对整个中华民族的最为严峻的挑战。资源的有效利用、环境的改善、经济和社会的发展 ,所有这一切都需要发展一种可靠的清洁能源。由于我国煤炭资源丰富、油气资源相当有限 ,从煤中寻找新型的能源载体已迫在眉睫。讨论了二甲醚 (DME)的性质、制备方法和用途 ;分析了其对经济、社会和环境的优势 ;阐述了在 2 1世纪前 30年内二甲醚是一种技术成熟、经济性好、污染排放介于石油和氢能之间的中国所需的能源。DME还是我国能源系统跨越式发展的最有前途的领域 ,也是中国最重要的能源载体之一。最后 ,指出中国应早日建立“DME经济” ,东西部应基于自身条件发展“二甲醚经济”。

DME Economy:the Key to the Problems of Energy and Environment of China

In the first 30 years of the 21 st century, the contradiction between resources, environment and population increases, and economic development will be the toughest challenge facing China.Using resources efficiently, improvement of the environment ,and the development of economy and society all require the development of a reliable and clean energy carrier. As China is rich in coal and lacking in oil and gas ,it is very urgent to find a new carrier produced from coal. The property, production and usage of Dimethyl Ether(DME) are discussed in this paper, and the great benefit to the economy,society and environment are also analyzed. Based on the analysis, the paper indicates that in the first 30 years of 21 st century, DME is exactly the fuel that China needs, as if has mature technology, good economy and emission between using oil and hydrogen. DME is also a field that China could use as a leap frogging technology for its energy system. The paper predicts that DME will be one of the important carriers of China's energy. Finally, the paper suggests that China should consider"DME Economy"as soon as possible, and Western China and Eastern China should develop"DME Economy"based on their various conditions.
