针对活性炭吸附煤烟气脱硫这种重要的工艺方法进行了研究。采用了多种方法将活性炭进行改性处理,最终确定用硝酸银作为改性剂并采用微波加热对活性炭进行改性处理。实验结果表明,此种改性活性炭比原始的活性炭吸附SO2气体的效果好。 Aiming at the important process of coal-flue gas desulfurization by activated carbon adsorption was studied. A variety of methods are used to modify the activated carbon, and finally determine the use of silver nitrate as a modifier and microwave heating of activated carbon modified. The experimental results show that the modified activated carbon is better than the original activated carbon in adsorbing SO2 gas.
