Scientists will succeed in making carbon dioxide turns into a carbon fiber.
Will artificially produced greenhouse gas carbon dioxide into a valuable commodity, has been the dream of scientists and government officials. Now, the George Washington university, a research team developed a carbon dioxide in the atmosphere directly into is very tight in the field of industrial and consumer carbon fiber technology, to promote the process of solving the problem of global warming.
Submit the new study. The study in the journal science, the George Washington university Stewart Hitt said: “we have found a way to use the enrichment of carbon dioxide in the atmosphere in the production of carbon nanofibers method. This kind of fiber can be made into a powerful carbon – carbon composite materials, used in the manufacture of the Boeing 787 “dreamliner”, high-end sports equipment, wind turbine blades and other series of products.”
According to the researchers, the study can contribute to global warming carbon dioxide into the most popular FRP carbon manufacturing raw materials. Lehi, calls his approach the “diamond” from the sky.
Lehi, said their method of high efficiency, low energy consumption, only a few volts of electricity, there is plenty of sun and large amounts of carbon dioxide.The system USES electrolytic synthesis of nanometer fiber: in 750 degrees centigrade high temperature molten carbonate cell, by nickel and steel electrode and dc made the dissolved carbon dioxide, carbon nanofibers can be formed in the steel electrode.
This system by hybrid and high concentrated solar system to provide heat and electricity.Lehi, estimates that the electrochemical process, solar thermal electricity costs about $1000 per tonne of FRP carbon fiber products, the operation of the system cost a few one hundred times than output value.
He said: “we calculated that about one over ten the size of the Sahara desert in a region, the method can be used to cut carbon dioxide in the atmosphere within the next 10 years to the level before the industrial revolution.”
The system is experiment, the researchers of the biggest challenges facing is how to accumulate experience and improve production capacity, produce the same size of nanofibers. Lehi, said: “we are rapidly expanding production, should soon be able to output in an hour of nanofibers.”
