Nitrogenoso sorbent in coal combustion. The present invention relates compositions sorventes for coal nitrogenosos contain components that reduce the level of mercury and / or sulfur emitted in the atmosphere after combustion.The compositions sorventes are added directly to the fuel before combustion; directly on the globe of fire during combustion, are added in the fuel before combustion and the combustion gas after the combustion zone; or are added completely in the gas combu Is after the combustion zone, preferably when the temperature of the combustion gas is at least 500 198 C.The compositions comprise a source of sorventes nitrate ions, a source of lons of nitrite, or a combination of sources of nitrate and nitrite. The sorventes are added as solids or as solutions in water. In various forms, the compositions sorventes still comprise a source of halogen such as bromine.
