Study on the associated removal of pollutants from coal-firing flue gas using biomass activated carbon pellets
A pilot-scale multi-layer system was developed for the adsorption of SO2/NOx/Hg from flue gas (real flue gases of an heating boiler house) at various operating conditions,including operating temperature and activated carbon materials.Excellent SO2/NOx/Hg removal efficiency was achieved with the multilayer design with carbons pellets.The SO2 removal efficiency achieved with the first layer adsorption bed clearly decreased as the operating temperature was increased due to the decrease of physisorption performance.The NOx removal efficiency measured at the second layer adsorption bed was very higher when the particle carbon impregnated with NH3.The higher amounts of Hg absorbed by cotton-seed-skin activated carbon (CSAC) were mainly contributed by chlorinated congeners content.The simultaneously removal of SO2/NOx/Hg was optimization characterized with different carbon layer functions.Overall,The alkali function group and chloride content in CSAC impelled not only the outstanding physisorption but also better chemisorptions.The system for simultaneously removal of multi-pollutant-gas with biomass activated carbon pellets in multi-layer reactor was achieved and the removal reults indicated was strongly depended on the activated carbon material and operating temperature.
