  • Systems and methods for removing materials from flue gas via regenerative selective catalytic reduction
    Patent number: 7758831
    Abstract: Regenerative selective catalytic reduction (RSCR) systems and processes are provided whereby NOx and CO levels in gases are reduced by mixing the gas with a reactant and then introducing the gas into an RSCR apparatus for treatment that entails heating the gas, causing the gas to undergo one or more catalytic reactions, and then directing the gas through a heat transfer area, to which the gas provides heat for use in connection with successive cycles of the RSCR process.
    Type: Grant
    Filed: January 16, 2009
    Date of Patent: July 20, 2010
    Assignee: Babcock Power Environmental Inc.
    Inventors: Richard F. Abrams, John Robert Harold
