Methods And Systems For Absorbing CO2 And Converting Same Into Gaseous Oxygen By Microorganisms

摘要

Methods and systems are described for the purification of contaminated air containing CO2, converting it into O2 by means of the use of microorganisms. Said methods and systems comprise the initial steps of capturing the air proceeding from a source of contaminated air containing CO2, such as an industrial plant, and subsequent physical catalysis of said contaminated air, passing it across plates which partially fix the CO2 in the form of calcium and/or magnesium carbonates. Subsequent to these steps the air is passed through fermenter tanks containing a culture comprising a biofamily of microorganisms and an organic inhibitor permitting maximum absorption of CO2 and emission of O2. By means of the methods and systems described the conversion of CO2 into O2 is achieved having an efficiency very superior to those of the prior art.

1. Method for the purification of contaminated air containing CO2 by means of microorganisms, comprising the steps of:
a) reception of air containing CO2 proceeding from a source of contaminated air; b) physical catalysis, wherein the air containing CO2 is passed across plates comprising calcium and/or magnesium salts, whereon part of the CO2 of the air becomes fixed in the form of calcium and/or magnesium carbonates;characterised in that the method moreover comprises the steps of:
c) fermentation, wherein the air proceeding from step b) is passed across a culture comprising a biofamily of microorganisms as well as at least one organic inhibitor selected from the group consisting of an alcohol, a ketone or a carboxylic acid in any combination thereof, in which step at least part of the remaining CO2 in the air becomes dissolved in the culture; and d) irradiation of said culture with light radiation of the visible light spectrum having a particular frequency, intensity and duration,such that photosynthesis is promoted in said microorganisms, causing a reduction in the CO2 content in the culture through absorption and/or digestion of said CO2 in the microorganisms and producing O2.
