• No.1-2 Capture and Oxidation Mechanism of Mercury in Coal Combustion Exhaust Gas

抄録

Coal combustion is one of the major mercury emission sources. The majority of mercury emissions from coal combustion is an elemental mercury. This is because oxidized mercury is water-soluble and easily captured, but on the other hand elemental mercury is water-insoluble and difficult to capture. In this study, we expected the De-NO_x catalyst to have a mercury capture/oxidation performance and performed mercury capture/oxidation experiment using the De-NO_x catalyst as a sorbent. In the result, when HCl is present in the atmosphere, the De-NO_x catalyst oxidized mercury and when HCl is not present in the atmosphere, the De-NO_x catalyst showed high mercury capture performance. Furthermore, De-NO_x catalyst maintained high mercury capture performance at a relatively high temperature (673 K).
