摘要
以Na/γ-Al2O3为吸附剂,研究了NO、SO2在该吸附剂上的吸附、脱附性能。结果表明:SO2很容易被吸附,而NO必须在SO2和O2存在时才能被大量吸附,SO2的吸附对NO的吸附具有促进作用;吸附剂中Na含量为7.8%,温度为100℃时NO、SO2的最大吸附量分别为0.0436mmol/g和0.264mmol/g。漫反射红外光谱分析结果表明,热脱附只能脱附出NOx,而不能把SOx脱附下来,从而达到了将NO和SO2分开治理的目的。
<Abstrcat> The adsorption-desorption properties of NO and SO_2 on Na/γ-Al_2O_3 adsorbent were investigate. The experimental results showed that SO_2 was adsorbed easily, but the adsorption of NO took place only in the presence of SO_2 and O_2, and the adsorption of SO_2 could promote the adsorption of NO .When the Na content reached 7.8% mass, under the adsorption temperature of 100 ℃, the adsorbing capability of this adsorbent to NO and SO_2 reached the maximum value of 0.0436mmol/g respectively . The studying of DRIFTs spectra showed that only NO_x could be desorbed from the adsorbent. Hence, the mixture of NO and SO_2 could be separated under this adsorbent.
