摘要
为探究O_2/CO_2燃煤烟气气氛下影响活性炭脱汞的因素,选取一种商用活性炭进行固定床吸附实验和程序升温热解脱附(TPD)实验。实验结果表明:与N_2相比,纯CO_2气氛对活性炭吸附Hg^0影响很小,但在模拟O_2/CO_2烟气气氛下,活性炭脱汞的性能要优于模拟O_2/N_2烟气气氛;对于活性炭脱汞,SO_2表现出抑制作用而NO表现出促进作用,在模拟O_2/CO_2和O_2/N2烟气气氛下影响规律表现一致。
To explore the influence of mercury removal by activated carbon under O2/CO2 flue gas atmosphere, a kind of commercial activated carbon was selected for adsorption experiments in a fixed bed reactor system and for temperature-programmed desorption experiments. Results show that compared with N2, pure CO2 atmosphere has little effect on Hg^0 adsorption by activated carbon. However, the activated carbon performs better in simulated O2/CO2 flue gas atmosphere than in O2/N2 atmosphere under same conditions. SO2 inhibits and NO promotes the mercury removal by activated carbon, and their influence trends are consistent in both the simulated O2/CO2 and the simulated O2/N2 flue gas atmosphere.
