Studies on Fluidized Bed Technology for Treatment of Gaseous Pollutants: Nitrogen Oxides(NOx)

Abstract

In a Fluidized Bed Reactor, which can be operated till a maximum of 500ºC, abatement of Oxides of Nitrogen needs to be done. The bed material chosen is manganese ore. The main fluidizing gas is compressed air and the oxides of nitrogen are fed as the secondary fluidizing fluid. The oxides of nitrogen are prepared in the laboratory itself. Along with the oxides of nitrogen, sulphur dioxide is also fed as the secondary gas for some of the experiments to check its effect on the abatement of oxides of nitrogen. Other than that temperature is also varied to see its effect. The residence time is another factor on which quality of fluidization depends hence it is also varied to check its effect on the abatement of oxides of nitrogen. Finally the characterization of the bed material before and after fluidization is done and compared to confirm the reduction in the quantity of oxides of nitrogen from what is initially fed to the Fluidized Bed Reactor.
