Experimental Study on Simultaneous Activated Carbon-based Desulfurization and Denitration Under Microwave Irradiation

To improve the removal efficiency of simultaneous activated carbon-based desulfurization and denitration under microwave irradiation, and to reduce the energy consumption and increase the selectivity of reduction reaction, several catalysts were chosen and loaded on the activated carbon to study their influences on the simultaneous desulfurization and denitration. Results show that the greater the microwave power is, the higher the temperature of activated carbon bed and the reaction temperature will be; the adding of catalyst can improve the efficiency of simultaneous desulfurization and denitration, and different catalysts produce different effects; under the microwave power of 420 W, copper-based catalysts can promote the activated carbon-based denitration but inhibit the activated carbon-based desulfurization under microwave irradiation. As the optimal catalyst in industry application, Mn (NO₃)₂ can help to improve the simultaneous desulfurization and denitration efficiency up to 95%.
