ABSTRACT:
An active carbon suspension obtained by mixing particles of active carbon with water, and flue gas containing sulfur dioxide are introduced into a desulfurization column, wherein the flue gas is contacted with the active carbon suspension. Sulfur dioxide is absorbed into the active carbon suspension, thereby purifying the flue gas. On the other hand, the absorbed sulfur dioxide is converted to sulfuric acid by a catalytic action of the active carbon in the desulfurization column, and the resulting sulfuric acid is separated from the active carbon suspension.
