In the information age, it is crucial to have knowledge about how things around us work. Even if you have questions such as why VPN is not working, all you need is internet connection in your phone or computer, and you will get all the information you need at the touch of a button.
That said, have you ever wondered how carbon dioxide is converted into fuel?
Well, you have come to the right place! Below are some of the ways in which this process takes place.
Using a catalyst
One of the most effective means of fuel production using carbon dioxide is through the use of a catalyst. One of the useful catalysts is palladium. The palladium-to-copper catalysts are used such that it increases the efficiency at which methanol, which is a fuel for combustible engines, is produced.
The catalyst looks by increasing the surface area of a non-porous pot which is recommended for the process. While palladium alone can also be used as a catalyst for the conversion, copper is added to increase the rate at which methanol is formed.
The catalysts also lower the energy requirements for the reaction and lead to the production of quality product.
Hydrogen-carbon dioxide reaction
Now that the catalyst has been introduced, hydrogen and carbon dioxide are all drawn into a sealed chamber. Remember that for this process to be effective and efficient conditions in the chamber need to be made conducive to vamp up the rate of the reaction. That entails the introduction of the catalyst too.
The chamber containing the contents that are, the catalyst, carbon dioxide and hydrogen, is brought to a maximum of 482 degrees Fahrenheit. Once the process is complete, there is usually a chance that some carbon dioxide and hydrogen will remain unconverted. The two elements can be recycled and returned to the chambers.
Carbon dioxide hydrogenation
Now that you know how methanol can be converted from carbon dioxide, you must be a little curious about where hydrogen for the process comes from. Well, here is how hydrogen is acquired. Water is decomposed such that hydrogen is produced with the use of renewable energy.Since methanol is the by-product of the process, you must be having questions regarding how it can be used as fuel. Apart from being used as fuel for internal combustion, it is used in the manufacture of other fuels. In other countries, it is used as a fuel for racing cars. Researchers continue to find new catalysts that will improve the efficiency of the process. Also, the process has made a significant contribution in controlling the levels in the atmosphere as it is usually where carbon dioxide is tapped from.
