After years of research and experimentation, Chinese scientists have oxidized methanol to the ether dimethoxymethane (trimethyl ether) and mixed this liquid substance with gasoline to mix a highly efficient ether-based clean gasoline. Methoxymethane gasoline.
This reporter learned from the demonstration of the industrialization of the dimethoxymethane gasoline project organized by the China Productivity Promotion Center Association of the Ministry of Science and Technology in Beijing on the 15th.
An expert group consisting of Jin Yong, a member of the Department of Chemical Engineering at Tsinghua University, and Hu Qianlin, a researcher of the National Productivity Promotion Center of the Chemical Industry, proposed to build an industrialization device as soon as possible on the basis of further optimization and improvement of the technology.
In recent years, as an alternative energy source, people often incorporate methanol and ethanol into gasoline. Because the water content of gasoline is 1% for methanol, and the water tolerance for ethanol is 5%, the difficulty in formulating and using methanol gasoline and ethanol gasoline impedes the development of alcohol gasoline.
As an oxygenated fuel, researchers from Sichuan University and Shenzhen Diane Energy Co., Ltd. conducted a systematic study of gasoline mixed with dimethoxymethane, and studied the principle, experimentality, and application. Ether clean gasoline has mechanical, combustion, toxicological, anti-knock, anti-corrosion, anti-swelling properties, and is performed on dimethoxymethane gasoline blended in 5%, 15%, 30% and 50% proportions. Physical and chemical indicators, engine benches, driving indicators and durability indicators.
The test results show that the new formula of ether clean gasoline can be ignited faster and more efficiently than ethanol gasoline. Compared with standard gasoline, gasoline with dimethoxymethane reduces emissions of carbon monoxide and hydrocarbons by about 70%, reducing the contribution of vehicle exhaust to PM2.5.
As the main developer of dimethoxymethane gasoline, Professor Liu Jinchao of Sichuan University said that the amount of dimethoxymethane blended into gasoline can reach 30%. To promote this alternative energy source can not only reduce dependence on gasoline, but also have It helps to improve energy cleanliness and reduce haze.
It is worth mentioning that as a raw material of this kind of high-efficiency ether clean gasoline, in addition to synthesizing methanol from coal and natural gas, researchers have also found a technical route for synthesizing dimethoxymethane from biomass: planting it on the barren land of a barren mountain. Giant genus grasses, followed by gasification to synthesize methanol, and then oxidize methanol to dimethoxymethane, opens up a path to a combination of alternative energy sources and renewable energy sources.
