Summary

The primary objective of this project is the investigation of the effects of pore structure on the capacity of porous metal oxides for removal of gaseous pollutants from flue gases of power plants (SO₂) and hot coal gas (primarily H₂A). Specifically, we intend to appropriately exploit the differences of the sulfidation and sulfation reactions (for instance, different molar volumes of solid products) to elucidate the dependence of the sorptive capacity of a porous sorbent on its physical microstructure. The following tasks have been identified in the proposed project: (1) Literature survey and identification of solids to be used in experimental studies. (2) Experimental study of the reaction of the chosen solids with SO₂ and/or H₂S. (3) Experimental study of the evolution of the structure of the solids during reaction with SO₂ and/or H₂S using pore structure analysis and effective diffusivity measurements. (4) Model testing and validation using the obtained experimental data.
