This work supports the program to develop methods for cleanup of combustion gases from pressurized fluidized-bed coal combustors so that the cleaned gases can be used to power downstream gas turbines without causing corrosion. A simulated PFBC flue gas was used in testing activated bauxite in a granular bed filter for its NaCl-vapor sorption performance at a bed temperature of 905/sup 0/C and a system pressure of 10 atm absolute. Greater than 99.8% NaCl-vapor capture efficiency was achieved. Changes in the activated bauxite's chemical properties as a result of exposure to the simulated flue gas are described, and possible explanations for the changes are discussed.
