Experimental Study on Simultaneous Desulfurization and Denitrification over Activated Carbon Carried Catalyst under Microwave Irradiation

Abstract

The influences of different catalysts added to the activated carbon were studied for reducing energy consumption and enhancing reaction selectivity while microwave irradiate activated carbon for removal of sulfur dioxide and nitrogen oxides. It was found that the addition of catalyst can lower the power of microwave needed for the same sulfur dioxide and nitrogen oxides removal efficiency to a large extent; moreover, different catalysts introduced would cause different effects, in which the zincous catalyst and manganese catalyst had more apparent catalytic effects, about 95% removal efficiency could be achieved under microwave power 420W. X-ray diffraction (XRD) was adopted to have a study of the microstructure of the activated carbon, and it is shown that some catalyst components do exist on the surface of the activated carbon
