Resumen
El carbón es uno de los combustibles fósiles más empleados para la producción de energía eléctrica, y para diferentes actividades industriales y domésticas. Sin embargo, el uso de este combustible genera emisiones nocivas para el ambiente; entre ellos se encuentra el CO2 , principal producto de combustión que actúa como gas de efecto invernadero. Se han estudiado diferentes procesos con el fin de disminuir la emisión de CO2 a la atmósfera, entre ellos se encuentra la oxi-combustión, que consiste en emplear una atmósfera enriquecida en O2 , con el fin de obtener una alta concentración de CO2 en los gases de combustión que facilite su separación. El incremento en la presión parcial de O2 genera cambios importantes en el ambiente químico de la combustión que afecta las reacciones de oxidación y emisión de contaminantes como SOx y NOx. En la presente investigación se encontró que en procesos de oxi-combustión, altas concentraciones de CO2 promueve la formación de NO2. Por lo tanto, es importante evaluar los efectos que tendrán estas modificaciones en el proceso global.
