| 摘 要： | 将CuO/γ-Al2O3用于烟气脱硫研究。考查了脱硫剂制备参数及反应条件对CuO/γ-Al2O3脱硫活性的影响。并对不同载铜量的脱硫剂进行了XRD表征。结果表明，载铜量的质量分数为8%～10%时，脱硫剂具有较高的脱硫活性，高于10%的载铜量致使活性组分CuO在Al2O3表面发生多层覆盖，活性位的利用率下降；在350 ℃～500 ℃的烟气温度及
3 000 L/kg·h～56 000 L/kg·h的操作空速范围内，CuO/γ-Al2O3具有较高的脱硫活性，烟气中的O2对于CuO/γ-Al2O3的脱硫活性是必需的，水的影响不大。

| Abstract: | CuO/γ-Al2O3 was used to remove SO2 from flue gas. The effects of catalyst preparation parameters and reaction conditions on sulfur removal activity were investigated. The characterization of the CuO/γ-Al2O3 desulphurizer with different Cu loading has been carried out by XRD. The CuO/γ-Al2O3 desulphurizer with 8%～10% Cu loading shows the highest activity for SO2 removal. The decrease of sulfur removal activity of CuO/γ-Al2O3 with Cu loading higher than 10% may be due to segregation of CuO on the surface of Al2O3. At temperatures of 350℃～500℃ and GHSV of 3 000 L/kg·h～56 000 L/kg·h, the CuO/γ-Al2O3 desulphurizer shows high sulfur removal activity which is greatly promoted by presence of oxygen in the simulated flue gas. |
