The significance of developing and applying dimethyl ether
Thread Content
It is very necessary to develop and apply dimethyl ether clean fuel to drive my country's economic development. Dimethyl ether has extremely broad development prospects as an alternative fuel for automobiles. If a quarter of the country's cars use dimethyl ether, an alternative energy source to petroleum, 15 to 20 million tons of gasoline can be saved every year. If all cars in the country use dimethyl ether fuel by 2010, about 80 to 100 million tons of dimethyl ether fuel will be needed every year. In this way, vehicle fuel can be based in China, make full use of my country's coal resources for on-site conversion, and convert coal mining into high-tech, high value-added new energy output. From the perspective of market prospects, dimethyl ether has a wide range of uses, and its production and application technology has become a research hotspot in the fields of energy, environment and chemical industry in the world today. It is a promising field for my country's future energy technology to achieve leapfrog development, and can drive the development of my country's new generation of automobile industry, electric power industry and civil fuel industry. With the success of dimethyl ether process technology and the realization of large-scale industrial production, the cost of dimethyl ether can be significantly reduced, and its downstream application fields will be further expanded. In particular, its prospects as an alternative automobile fuel or civil fuel are very bright, and it will play an immeasurable role in the overall development of our country's economy.
. . . Dimethyl ether is mainly used to replace diesel because of its high cetane number and is suitable for compression ignition engines.
How easy is it to replace diesel? Although dimethyl ether can theoretically replace diesel, is it economically comparable?
Combining theory with practice, dimethyl ether is now mainly used to mix liquefied gas, and the supply exceeds demand. As for cars, etc., they are still in the experimental stage and there is still a long process to go before they can be put into use. Relevant standards also need to be introduced, and local and* * Policy encouragement. The cause of dimethyl ether has a long way to go!
Dimethyl ether as an aerosol, refrigerant, etc. also has a market of about 1 million tons per year.
