This work supports the program to develop granular sorbents for the control of alkali vapors from pressurized fluidized-bed combustion (PFBC). A laboratory-scale pressurized test unit was used to characterize two potential sorbents identified earlier, activated bauxite and Emathlite. Experimental tests have been conducted to measure the rate of alkali (Na + K) evolution from the sorbent material itself in a gas stream with temperature (850/sup 0/C), pressure (10 atm absolute), and composition closely simulating actual PFBC flue gas. The rate was then used to evaluate the significance of the alkali evolution for its possible effect on the turbine by comparing with the currently accepted alkali tolerance of an industrial gas turbine. A laboratory-scale demonstration of use of a granular-bed sorber for the control of alkali vapors from PFBC has been initiated. Details of a high temperature/high pressure sorber system designed for this demonstration are discussed. 12 references, 5 figures, 2 tables.
