· ABOUT THIS BOOK
Economic andenvironmental requirements for advanced power generating systems demand theremoval of corrosive and other sulfurous compounds from hot coal gas. After abrief account of the world energy resources and an overview of clean coaltechnologies, a review of regenerable metal oxide sorbents for cleaning the hotgas is provided. Zinc oxide, copper oxide, calcium oxide, manganese oxide basedas well as supported and mixed metal oxide sorbents are treated. Performanceanalysis of these sorbents, effects of various parameters on thedesulfurization efficiency, kinetics of sulfidation and regeneration reactions,sulfiding and regeneration mechanisms are discussed. Two chapters presentrecent results in the direct production of elemental sulfur from regenerationor SO2-rich gases.
