Title: Screening of granular sorbents for the removal of gaseous alkali metal compounds from hot flue gas

Abstract

Six commercially available sorbent materials have been tested as granular sorbents to be used in granular-bed filters for the removal of gaseous alkali metal compounds from the hot (800 to 880/sup 0/C) flue gas of pressurized fluidized-bed combustors (PFBC) for proposed combined-cycle power generation. Tests were performed by passing simulated relatively dry flue gas of PFBC through granular-bed filters in either a laboratory-scale, fixed-bed combustor or a high temperature sorption test rig. The experimental results of screening tests are presented. Diatomaceous earth and activated bauxite were found to be the two most promising sorbents. Possible sorption mechanisms and applications of the sorbents are discussed. 3 figures, 7 tables.
