Method for the treatment of activated carbonaceous material containing alkali/alkaline earth metals for the reduction of NOx from flue gas |
| abstract |
Economical NOx reduction from the flue gas is essential for the long-term profitability and existence of fossil fuel based thermal power plants. The proposed process describes the application of activated carbonaceous materials for the post-combustion control of nitric oxide (NOx) emissions from flue gas. Integral experiments were carried out on a variety of carbonaceous species such as graphite, activated carbons and coal char. A selectivity parameter (g carbon consumed/g NO reduced) has been used as a basis for quantifying the effect of the various parameters such as oxygen concentration, alkali impregnation and temperature of reaction on the carbon-NO selectivity. The reaction between pure structured carbon (graphite) required very high temperature. The reaction rate with char and activated carbon was determined to be higher compared to the rate with graphite. The reaction temperature was significantly reduced by the impregnation of carbons with alkali metals. For a given carbon, the selectivity of the carbon-NO reaction increased with temperature. The effect of initial surface area of the carbon was also studied on sodium carbonate impregnated activated char. It was seen that a higher initial surface area increased the selectivity of carbon-NO reaction. |
