Carbon dioxide can also be transformed into gasoline

Carbon dioxide, widely regarded as the culprit of global warming, combined with a catalyst, can "transform" into gasoline and build an inexhaustible oil field? This fanciful idea has been turned into reality by scientists Recently, scientists from Dalian Institute of chemical engineering, Chinese Academy of sciences have discovered a new process of efficient conversion of carbon dioxide They have designed a new multifunctional composite catalyst to directly hydrogenation carbon dioxide to produce high octane gasoline for the first time How does carbon dioxide make gasoline? There are many difficulties in the process of producing gasoline from carbon dioxide The CO2 molecule is relatively stable and difficult to activate Secondly, in the aspect of selective conversion, the catalytic reaction of CO2 and hydrogen molecule is easier to generate small molecular compounds such as methane, methanol, formic acid, and it is difficult to generate long-chain liquid hydrocarbon fuel Based on this, scientists have developed a highly efficient and stable multi-functional composite catalyst, including three compatible and complementary active sites: Fe3O4, Fe5C2 and acid site Carbon dioxide is transformed with the help of these three active sites Precise control of the structure and spatial arrangement of the three active sites is the key to the realization of CO2 hydrogenation to gasoline Specifically, CO2 is first reduced to CO at the Fe3O4 active site by reverse water gas conversion reaction; the co generated is converted to α - olefin by Fischer Tropsch reaction at the Fe5C2 active site; then, the olefin intermediate is transferred to the acid site on the molecular sieve to selectively generate gasoline distillate What are the advantages of CO2 to gasoline? There are many advantages in the production of gasoline from carbon dioxide, mainly reflected in environmental protection, economy and other aspects First of all, carbon dioxide is the source of greenhouse effect If it is recycled and made into gasoline, it is conducive to the development of green and environmental sustainable development Second, as a potential alternative to fossil fuels, clean and renewable fuels, the gasoline produced by carbon dioxide can reduce the dependence on traditional fossil energy At the same time, the recovery and utilization of carbon dioxide can achieve some economic benefits Moreover, the technology can open up new ways for the utilization of intermittent renewable energy such as wind energy, solar energy, water energy, etc The composite catalyst developed by the scientists has good stability and can run stably for more than 1000 hours, laying a foundation for the stable production of this kind of gasoline Today, with the promotion of clean energy as the main part, the use of carbon dioxide to produce gasoline can build an "inexhaustible" large oil field, which has a broad potential application prospect.
