In spite of the worry by the global warming, the low cost of extraction of the fuels fossils and his constant use, especially in the emergent countries, is causing that the levels of atmospheric pollution by the broadcasts of CO
2 are still in increase. Different studies of prospectiva energetic propose the capture and storage of CO
2 like one of the big solutions to reduce the atmospheric pollution. A group of Spanish researchers is experiencing how a simple chemical reaction can diminish the broadcasts of carbon dioxide.
The professor Carlos Abanades gives to know today Tuesday 15 in the frame of the Scientific Coffees that celebrate in Expoquimia, the International Living room of the Chemistry of Fira of Barcelona, the results of the pilot experience that a team of scientists of the Institute of the Coal of the Upper Council of Scientific Investigations (INCAR-CSIC), under his direction, is carrying out in the thermal head office of The Robla (León).
The group of Carlos Abanades uses the oxide of calcium (cal) and puts it in contact with the gases contaminantes in such a way that it produces a chemical reaction called carbonatation. As it joins to the cal, remaining trapped in a material (the calcic carbonate) and pouring like this to the atmosphere some smokes with lower quantity of CO
2. The CO
2 captured goes to stop to a geological warehouse underground controlled.
Abanades Signals that “in the International Year of the Chemistry, have to celebrate that we have a very solid experience in processes of separation of gases” like which allows the capture of the carbon dioxide and that gives solution to a grave problem. In his presentation, the professor Abanades will stand out the importance of the participation of the business world in this type of experiences and will show how this process can apply so much in head offices that use coal like biomass.
