German Audi Automobile Company's New Fuel Laboratory Successfully Synthesized 'e Diesel'
Reprinted from Science and Technology Daily. On May 4, the new fuel laboratory of German Audi Automobile Company cooperated with Sunfire, a new energy company in Dresden, and recently successfully developed a process for producing diesel using carbon dioxide and water. This new process for synthetic diesel is expected to be used in atmospheric protection and resource utilization. open up a whole new way. It is reported that this is called“e diesel”The basic principle of the 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: first, the water is evaporated in the boiler, and the water is electrolyzed into hydrogen and oxygen at a high temperature of 800 degrees Celsius. This is an ordinary water electrolysis technology. The electricity used in the electrolysis process is the surplus ecological electricity 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, which are called“Blue Crude”The hydrocarbons have an energy conversion efficiency of 70%, which is no less than the energy conversion efficiency of fossil fuels, and does not contain sulfur and aromatic hydrocarbon impurities, and has a high cetane number (indicating the spontaneous combustion index of diesel fuel when it is burned in a diesel engine). , low ignition point and other characteristics. It is understood that in the project laboratory in Dresden, 160 liters of synthetic diesel can be made per day using this new process. Although the current output is still very small, if industrial production can be realized, the future application prospects are immeasurable . According to project leader Mangold, Audi's“e fuel”An important addition to electric vehicles, the use of carbon dioxide as a fuel is not only an innovation for the automotive industry, but can also be applied in other fields. According to reports, the German Federal Ministry of Education and Research has given support to this project. Minister of Education and Research Wanka said that if the project is successful,“CO2 can then be used as a feedstock, which will make a decisive contribution to atmospheric protection, resource efficiency, and the path to a green economy”.
