  • China's crude oil production is far from meeting the needs of the domestic economy.
  • Today, China has become a net importer of crude oil from crude oil exporting countries, and most of China's crude oil is dependent on imports. The intensification of this situation will seriously restrict the further development of China's economy and even affect China's national defense security. Therefore, it is necessary to find a vehicle fuel that does not require the use of petroleum raw materials, and thus does not require the import of petroleum from abroad.
  • Benzene is a recognized carcinogen. It is directly affected by the evaporation and combustion of gasoline and the release of exhaust gas into the atmosphere. Therefore, the EU, UK, Australia and Russia gasoline standards all limit this indicator, generally specified as not more than 5% (v/v) Stamm Beijing local standard Precisely, the content of benzene is required to be not more than 1.0% by volume. However, as environmental requirements, governments and relevant agencies may also impose more stringent restrictions.
  • An aromatic hydrocarbon is a gasoline blending agent with a high octane number and a high calorific value. However, it burns to cause the formation of carcinogenic benzene, and it tends to increase the carbon deposits in the combustion chamber and increase the CO 2 emissions. It is generally believed that the greater the content of benzene and other aromatic hydrocarbons in gasoline, the greater the benzene content of the combustion products. Therefore, reducing the aromatics content in gasoline is bound to benefit the environment by reducing benzene emissions from the tail gas.

Abstract

L'invention concerne un nouveau combustible propre et, particulièrement, un combustible propre à base d'éther qui comprend un éther diméthylique, un méthanol et 2,6-di-tert-butyl-4-méthylphénol. Plus particulièrement, ce combustible à base d'éther est constitué d'éther diméthylique, de méthanol et de 2,6-di-tert-butyl-4-méthylphénol. Ce combustible à base d'éther peut remplacer l'essence dans les automobiles, dans les autres véhicules ou équipements énergétiques à moteur à essence. L'invention concerne en outre un combustible mixte comprenant le combustible à base d'éther de cette invention et de l'essence.
