| 摘 要： | 活性焦载体的选择是制备高活性烟气脱硫催化剂的关键.以四种煤制活性焦(AC)为载体,制得了系列V2O5/AC催化剂.通过脱硫活性评价、催化氧化能力测试和孔结构分析表明,AC表面的高活性氧化位较少,担载V2O5使AC表面产生了新的高活性氧化位,其脱硫活性显著提高；V2O5在具有高比表面积和较大孔容的载体上分散性较好,能够形...

| Abstract: | Properties of activated coke(AC) are very important for preparing the V2O5/AC catalysts of high activity for flue gas SO2 removal.Four ACs as the catalyst carrier are studied in this work,and the experiments include the measurements of SO2 removal activity,oxidation activity and pore structure.The ACs are found to have few sites of high oxidation activity.The loading V2O5 leads to a high oxidation activity and much increased SO2 removal activity.The well developed pore structure of the ACs is attributed to ... |
