  • 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 indicator is restricted in the EU, UK, Australia and Russia gasoline standards, generally not more than 5% (v/v). According to Beijing local standards, the content of benzene is required to be no more than 1.0% by volume. However, as environmental requirements, governments and relevant agencies may also impose more stringent restrictions.
