A catalyst system using a special support material is proposed for simultaneous treatment of gaseous pollutants SO2, CO, NO., and hydrocarbons as well as particulate matter in flue gases from power plants. Preliminary experiments on one of the proposed catalysts show promising results for simultaneous conversion of gaseous pollutants. Phase I research and development program proposes reaction kinetic studies with prepared catalysts to understand the potential and limitation of the catalyst system for treatment of power plant emissions.
