The spheres are formed at 800°C. By Trevor English Dec 30, 2020 Carbon capture technology allows the re-capturing of carbon from the air as well as the collection of carbon from various emissions sources. One of the most vital components of this process is the production of carbon-capturing spheres. These spheres function by capturing carbon from the air and converting the CO2 into solids. This allows the CO2 to easily be stored and kept from polluting the atmosphere in a gaseous form. Researchers at Swansea University have developed a new way to produce these carbon spheres that can be scaled effectively. Carbon spheres in their own right range in size dramatically. They can be anywhere from a few nanometers to a few micrometers and are commonly used in many environmental treatment processes like water treatment, gas storage, and even drug delivery.
