Cutting-edge research project funded under the European Commission's Sixth Framework Program (FP6) has resulted in the discovery of a method for converting carbon dioxide (CO2) releases into useful fuel .



This STREP (Specific Targeted Research Project) entitled ELCAT, is a joint venture of the Max Planck Institute (Germany), Louis Pasteur University (France) and the University of Patras (Greece ), coordinated by researchers from the University of Messina (Italy). The project is funded under the New and Emerging Science and Technologies (NEST) program of FP6.



The project team explored how to capture the “lost” carbon in CO2, the most common release resulting from the combustion of fossil fuels and the most important greenhouse gas, largely responsible for global warming.



While CO2 is not the most dangerous greenhouse gas, it is by far the most abundant, and atmospheric CO2 levels, which are tightly controlled, show a disturbing correlation with temperature increases. air and oceans.



"The conversion of CO2 into fuel is not a dream, but an effective possibility that requires further research," said the team's director, Professor Gabriele Centi of the University of Messina, in an interview with the journal New Scientist.



The results of this project, once refined, could help transform the dream into reality, namely to capture the CO2 present in the atmosphere to convert it into useful fuel. One of the problems with CO2 is its extreme stability. Once formed, the chemical valences of CO2 are extremely difficult to break. The new technique allows special catalysts to break these valences and create long carbon chain molecules that can easily be converted into fuel.

We can rightly speak of avant-garde research.



Normally, it takes enormous energy to break down these chemical valences, even by catalysis. The researchers used a two-step method. First, sunlight was combined with a titanium catalyst to break down water molecules, thereby releasing "protons" (hydrogen ions) and free electrons and oxygen. Then, these free electrons are used to reduce the CO2 and to bind the carbon atoms between them by means of platinum and palladium catalysts placed inside carbon nanotubes.



To the astonishment of the researchers, the method is efficient enough to produce molecules of eight or nine long hydrocarbon chains at one percent efficiency at room temperature, i.e. it is already two to three more efficient than any other industrial process. If combined with "green" technologies, such as the enormous mass of heat generated by solar thermal towers, one could achieve an even higher degree of efficiency.



In a presentation to the American Chemical Society in San Francisco on September 13, Professor Centi said that viable production of hydrocarbon chains from CO2 could begin "in a decade."

Well ... well here is a good idea ... to materialize QUICKLY because it HEATS.

A topic in the December S&V was devoted to this technique.

To put it simply I would say: "Not profitable enough my son" (see old pub clio)
