METHODS AND SYSTEMS FOR ABSORBING CO2 AND CONVERTING SAME INTO GASEOUS OXYGEN BY MEANS OF MICROORGANISMS

摘要

Methods and systems are described for the purification of contaminated air containing CO 2 , converting it into O 2 by means of the use of microorganisms. Said methods and systems comprise the initial stages of capturing the air proceeding from a source of contaminated air containing CO 2 , such as an industrial plant, and subsequent physical catalysis of said contaminated air, passing it across plates which partially fix the CO 2 in the form of calcium and/or magnesium carbonates. Subsequent to these stages the air is passed through fermenter tanks containing a culture comprising microorganisms, and the culture is then passed through a tubing circuit wherein it is irradiated with light radiation of particular frequencies, intensities and durations, achieving maximised production of O 2 . By means of the systems and methods described the conversion of CO 2 into O 2 is achieved having an efficiency very superior to those known in the prior art.
