Can CO2 be converted into fuel?
Conversion of CO2 into fuel:
Conversion of CO2 into fuel is listed below.Synthetic gas or synthetic gas is an important basic ingredient in the chemical industry, and although most of us have never heard of this type before, it is used daily in the manufacture of medicines, fertilizers, plastics and biofuels.
Unfortunately, the process of obtaining energy using this synthetic gas (which is a mixture of hydrogen and carbon monoxide) is not always carbon-free or environmentally friendly, as most of the time the production of this combined gas requires the use of natural gas or carbon residues.
But this could be avoided 1 as Australian researchers discovered an easy and inexpensive way to manufacture this synthetic gas from carbon dioxide.
This is a very exciting step. Engineers have tried hard over the past years to achieve them, but they have discovered that it is expensive and difficult to implement.
The researchers discovered that at one stage in the synthesis of zinc oxide at high temperatures, nanoparticles that are ideal for use as catalysts for converting carbon dioxide into synthetic (synthetic) gas are released.
Zinc oxide is a cheap metal available, unlike many of the previously used catalysts.
“We can count on a steady source of carbon dioxide, such as coal plants, gas power plants or natural gas mines,” said chemical engineer Emma Lovell from the University of New South Wales. “Huge quantities of pure carbon dioxide are released, so we capture it to turn it into something useful for industry.”
This method is effective as it constitutes a closed end of the carbon cycle, however we still have a lot to do before expanding this method and applying it in practice, but given the widespread use of synthetic gas and its sustainable production, it is worth pursuing.
Synthetic gas consists of two primary components:
hydrogen and carbon monoxide, both of which can be used to make a complete package of industrial biochemicals.
Unfortunately, most of the synthetic gas in the world is made from methane (one of the gases that causes the most global warming), by using steam at high temperatures.
Thus, given the current climate crisis, a more sustainable alternative must be found, and the method the Australians devised is well suited; It takes only 10 minutes to burn zinc oxide without sophisticated techniques to produce nanocatalysts, and they are then used in electrolyzers designed to deal with residual carbon dioxide.
Chemical engineer Rehman Dayan of the University of New South Wales explains:
“The carbon dioxide residue from power plants or cement factories can be passed through the electrolyzer containing zinc oxide negatively, and the electricity processes the carbon dioxide residue to produce synthetic gas (a mixture of hydrogen and carbon monoxide) ) That comes out of the outlet ».
By controlling the amount of zinc oxide burning, different percentages of synthetic gas can be obtained according to the requirements of different industries.
We still haven’t found a way to apply this technology in power plants, but researchers are confident that their method is more appropriate and more likely to be developed in the future compared to other options.
Scientists are now preparing to test their method on a larger and more complex scale to verify its applicability in power plants, where chemical conditions are harsh.
