Due to the generation of a wide variety of pollutants during coal combustion, research on the development of a multifunction sorbent for adsorbing SO{sub 2} and alkali compounds simultaneously is ongoing at the University of Arizona. The current work focuses on the thermodynamic behavior of the reacting system for alkali adsorption especially in gas phase. The temperature and pressure effects on sodium species and on the system are intensively investigated under the simulated flue gas composition condition. The interaction of sulfur dioxide with sodium chloride vapor and some other system elements is also explored.
