Alternative formulations of regenerable flue gas cleanup catalysts
The major source of man-made SO{sub 2} in the atmosphere is the burning of coal for electric power generation. Coal-fired utility plants are also large sources of NO{sub x} pollution. Regenerable flue gas desulfurization/NO{sub x} abatement catalysts provide one mechanism of simultaneously removing SO{sub 2} and NO{sub x} species from flue gases released into the atmosphere. The purpose of this project is to examine routes of optimizing the adsorption efficiency, the adsorption capacity, and the ease of regeneration of regenerable flue gas cleanup catalysts. We are investigating two different mechanisms for accomplishing this goal. The first involves the use of different alkali and alkaline earth metals as promoters for the alumina sorbents to increase the surface basicity of the sorbent and thus adjust the number and distribution of adsorption sites. The second involves investigation of non-aqueous impregnation, as opposed to aqueous impregnation, as a method to obtain an evenly dispersed monolayer of the promoter on the surface.
