This work supports the program to develop methods for achieving sufficient cleanup of combustion gases from pressurized fluidized-bed coal combustors (PFBC) so that the cleaned gases can be used to power downstream gas turbines without causing corrosion. A simulated PFBC flue gas was used to characterize the NaCl-vapor sorption behavior of activated bauxite at a bed temperature of 905/sup 0/C and a system pressure of 10 atm absolute. Although the addition of HCl to simulated PFBC flue gas tends to promote the capture of NaCl vapor by activated bauxite as NaCl rather than Na/sub 2/SO/sub 4/, overall, its effect on the activated bauxite's NaCl-vapor sorption behavior was found to be insignificant. Experimental results are also presented on: (1) the partial conversion to Na/sub 2/SO/sub 4/ of the NaCl sample used as the source of NaCl vapor for the test system; and (2) the water leachability of the sodium captured on activated bauxite.
