Research on carbon loss in the process of desulfurization and denitrification using activated carbon irradiated by microwave
Abstract：Microwave heating technology coupling with adsorption performance and reduction capability of activated carbon can achieve high SO2 and NOx removal efficiencies,but some carbon loss may present in this process.Experimental studies of microwave power,oxygen content,activated carbon mass and irradiation time influencing on the carbon mass loss in microwave field were carried out.The rate of activated carbon loss increases along with the improvement of microwave power,and the longer the irradiation time,the higher the mass loss rate of activated carbon,the activated carbon wears down seriously in 150 seconds.The rate of activated carton loss also increases gradually with the rising of oxygen content.In the range of 2% and 4% of oxygen content,the loss rate of activated carbon is significant.The loss rate of activated carbon decreases linearly with the increasing activated carbon amount.BET results show that the specific surface area of activated carbon declines and average pore size increases under condition of microwave irradiation.
