The new fuel laboratory of Audi AG of Germany successfully synthesized 'e diesel'
Reprinted from Science and Technology Daily by Standard Group. On May 4th, the New Fuel Laboratory of the German Audi Automotive Company and Sunfire, a new energy company in Dresden, have recently successfully developed a process for producing diesel using carbon dioxide and water. This new synthetic diesel process is expected to be used in atmospheric protection and resource utilization. To open up a brand-new approach. It is reported that the basic principle of this so-called 'e diesel' project is to use electricity to convert into liquid fuel (PtL), the raw materials are carbon dioxide and water. The production steps are very simple: the first is to evaporate the water in the boiler and electrolyze the water into hydrogen and oxygen at a high temperature of 800 degrees Celsius. This is an ordinary water electrolysis technology. The electric energy used in the electrolysis process is the surplus ecological electric energy during the low peak period of the power grid. The second step is to synthesize the hydrogen and carbon dioxide obtained by electrolysis at high temperature and high pressure to generate long-chain liquid hydrocarbons. This hydrocarbon called 'Blue Crude' has a 70% energy conversion efficiency. The energy conversion efficiency is no less than that of fossil fuels, and it does not contain sulfur and aromatic impurities. It has the characteristics of high cetane number (indicating the self-ignitability index of diesel when burning in a diesel engine) and low ignition point. It is understood that in the project laboratory in Dresden, 160 liters of synthetic diesel can be made using this new process per day. Although the current output is still very small, if industrial production can be achieved, the future application prospects are immeasurable. . Project leader Mangold said that Audi's 'e-fuel' will be an important supplement to electric vehicles. The use of carbon dioxide as a fuel is not only an innovation for the automotive industry, but can also be used in other fields. According to reports, the German Federal Ministry of Education and Research has supported this project. Vanka, the Minister of Education and Research, stated that if the project is successful, 'carbon dioxide can be used as a raw material, which will contribute to atmospheric protection, resource efficiency, and a move towards a green economy.'
