本研究以烟煤为原料，软锰矿为催化剂，采用调合法制备了一种新型活性焦炭。采用BET、傅里叶变换红外光谱、X-射线光电子能谱和X-射线衍射仪对制备的活性焦物化性能进行了表征。结果表明，混合软锰矿对AC的结构性能影响不大，但AC上的含氧官能团增加，软锰矿中的MnO2和Fe2O3在AC-P样品中分别还原为MnO和Fe。所有AC-P样品的脱硫率均有显著提高，其中添加8 wt%软锰矿的AC的硫容最高，为153 mg/g，比空白活性鸡高57.7%。这主要归因于AC-P样品表面化学性质的变化和软锰矿在脱硫过程中催化氧化SO2的活性组分的变化。
In this study, a novel activated coke (AC-P) was prepared by the blending method using bituminous coal as the raw material and pyrolusite as the catalyst. The physicochemical properties of prepared activated coke (AC) were characterized by BET, Fourier-Transform Infrared Spectroscopy, X-ray photoelectron spectroscopy and X-ray diffraction. The results indicated that the blended pyrolusite had a slight effect on the structural properties of AC, while the oxygenated functional groups on AC were increased and MnO2 and Fe2O3 in pyrolusite were reduced to MnO and Fe on the AC-P samples, respectively. All the AC-P samples significantly improved the removal of SO2, with the highest sulphur capacity (153 mg/g) for the AC blended with 8 wt% pyrolusite, which was 57.7% higher than that of the blank activated cock. This could be mainly attributed to the change in surface chemical properties of the AC-P samples and the active catalytic components in pyrolusite for the catalytic oxidation of SO2 in desulphurization process.
