Abstract
Official abstract text for this publication.
The present invention relates to a method of reducing carbon dioxide and air pollutants, and more particularly to a method of simultaneously reducing emissions of carbon dioxide and air pollutants, in which an off-gas containing carbon dioxide, SOx, and NOx is passed through a sulfur-oxidizing microorganism reactor, thereby converting carbon dioxide present in the off-gas into biomass, SOx into sulfate ions, and NOx into amino-N.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of reducing carbon dioxide, SO x and NO x simultaneously comprising passing an off-gas containing at least one selected from the group consisting of carbon dioxide, SOx, and NOx through a sulfur-oxidizing microorganism reactor, wherein a sulfur-oxidizing microorganism is a microorganism that grows using reduced sulfur as an energy source and carbon dioxide as a carbon source, and is at least one selected from the group consisting of Acidithiobacillus, Thiosphaera, Thermothrix, Beggiatoa, Thioploca, Thiodendron, Thiobacterium, Macromonas, Achromatium, Thiospira, Thioalkalimicrobium, Thioalkalispira, Sulfolobus and Acidianus. 2. The method of reducing carbon dioxide, SO x and NO x simultaneously of claim 1 , wherein the off-gas is generated during a process in a power plant or a steel mill.
