From the Recent National Promotion of Ethanol Gasoline to See the Future of New Energy Vehicles (2)

Large-scale preparation of bio gasoline requires transesterification. The key technology in the synthesis of ethanol gasoline is the choice of catalyst. Phosphotungstic acid or silicotungstic acid is a tungstic heteropoly acid salt. It is an environmentally friendly catalyst widely used in recent years. They have strong generation acidity. 

The complex catalysis based on tungstic heteropoly salts can eliminate the problem of strong acid pollution in the process of ethanol gasoline synthesis, and can effectively control the cost, making ethanol gasoline a truly environmentally clean new energy.

In the same way, the main reaction process of hydrogen fuel cell or methanol fuel cell also needs to be used as an electrocatalyst. With the development of nanotechnology, tungsten carbide has also developed more functional packages. The study found that the presence of carbon in tungsten carbide changed the electronic properties of tungsten surface and made it have similar properties with platinum catalysts. The above views were confirmed by comprehensive comparison and experimental analysis of W, WC and Pt at home and abroad. As is known to all, platinum catalysts are rare and expensive, and 80% of the world's platinum metals are produced in South Africa. But tungsten resources are different. China has an advantage in tungsten resources and total reserves of rare earth resources. Nano tungsten carbide based composites are used instead of platinum.

Nowadays, the main problem of popularizing ethanol gasoline is the compatibility of vehicle engines. The main problem of popularizing hydrogen fuel cells is the cost of hydrogen production, but these will only be a matter of time. From the recent Shenhua Group's renamed "the national energy group" and the "coal hydrogen production" project, we can see that many enterprises at home and abroad have been actively layout and strive to occupy the commanding heights of hydrogen fuel energy.

Even though lithium battery is developing rapidly, it will still be difficult to replace the leading position of gasoline in the future, the future of new energy addition to solar cars, instead of gasoline dominance may be a liquid refillable new clean fuel. In the trade-off between lithium battery and hydrogen fuel cell, the new energy research field is in the front of Europe and the United States and Japan. More experts and scholars are more optimistic about the development direction of hydrogen fuel cell. Just look at China, and analyze the huge population and the amount of car ownership. If all the use of rechargeable energy, the power grid will be under greater pressure. When the supply is in short supply, the price of electricity will no longer be cheap. In addition, many areas in China are dominated by fire power plants, and coal combustion power generation is also a variable atmosphere pollution, less than gasoline. With more and more technological success, such as nano tungsten carbide and other more solutions, the production cost of other clean energy such as hydrogen energy will be greatly reduced, and large-scale popularization will be more likely.
