制备方法对MnOx鄄TiO2吸附剂脱汞及抗硫性能的影响

针对燃煤烟气中单质汞(Hg⁰)不溶于水很难去除和锰基吸附剂抗硫能力差的问题,以浸渍法、溶胶鄄凝胶法和沉积鄄沉淀法等三种方法制备MnO_x 鄄TiO₂ 为吸附剂,在固定床实验台架上考察了制备方法对MnO_x 鄄TiO₂ 吸附剂Hg⁰ 吸附量和抗硫性能的影响;利用N₂ 吸附/ 脱附、TG鄄DSC、XRD、TEM、H2鄄TPR 和XPS 等手段对吸附剂进行表征。结果表明,制备方法对MnO_x 鄄TiO₂ 吸附剂的脱汞活性影响颇大;沉积鄄沉淀法制备的MnO_x 鄄TiO₂ 吸附剂具有较高的Hg0 吸附量和抗硫能力。吸附剂的BET 比表面积高低与其脱汞活性无直接相关性;与浸渍法和溶胶鄄凝胶法相比,沉积鄄沉淀法制备的MnO_x 鄄TiO₂ 吸附剂不但可以增强其还原性和MnO_x分散度,而且还会显著提高吸附剂表面Mn⁴⁺/Mn 的比率和表面化学吸附态氧含量,进而增强吸附剂的脱汞活性和抗硫性能。
