Modified activated coke was prepared by the introduction of MnO_x, CeO_x, and M (FeO_x, CoO_x) into non-pitch coal-based activated coke (NPAC) using a novel non-pitch binder. The modified non-pitch coal-based activated coke was characterized in detail by N₂ physical adsorption, thermogravimetric analysis, X-ray diffraction, X-ray photoelectron spectroscopy, fourier transform infrared spectroscopy, temperature-programmed reduction of H₂, temperature-programmed desorption of NH₃, and its catalytic activity was examined by the selective catalytic reduction of NO with NH₃ at low temperature. In addition, the SO₂ and H₂O tolerance was investigated. The results indicated that compared to MnO_x–CeO_x–4.39, Mn–Ce–Co/NPAC-7 and Mn–Ce–Fe/NPAC-7 exhibit considerably higher catalytic activities while simultaneously maintaining NO_x removal rates of 78.98% and 77.85%, respectively, at 150 °C. The high catalytic performance of Mn–Ce–Co/NPAC-a and Mn–Ce–Fe/NPAC-a is related to several better properties compared to MnO_x–CeO_x–4.39, namely, considerably higher specific surface areas and percentages of O_α/(O_α+O_β+O_γ) and Ce³⁺/(Ce³⁺ + Ce⁴⁺), more easily reduced of Mn species, high reducibility, and more acidic sites. Furthermore, Mn–Ce–Co/NPAC-7 and Mn–Ce–Fe/NPAC-7 exhibited specific resistance to SO₂ and H₂O poisoning, and the SO₂ deactivation mechanism was proposed.

通过使用新型非沥青粘结剂将MnO _x，CeO _x和M（FeO _x，CoO _x）引入非沥青煤基活性焦（NPAC）中来制备改性活性焦。通过N ₂物理吸附，热重分析，X射线衍射，X射线光电子能谱，傅里叶变换红外光谱，H _2的温度程序化还原，温度程序化，对改性的无沥青煤基活性焦进行了详细表征。NH _3的解吸，并通过在低温下用NH ₃选择性催化还原NO来检查其催化活性。另外，SO ₂研究了H ₂ O的耐受性。结果表明，相比于MnO的_X -CeO _X -4.39，锰6 -钴/ NPAC-7和Mn 6 -铁/ NPAC-7表现出相当高的催化活性，同时保持NO _X的78.98％和77.85去除率分别在150°C下为％。Mn–Ce–Co / NPAC-a和Mn–Ce–Fe / NPAC-a的高催化性能与MnO _x –CeO _x –4.39相比具有更好的性能，即比表面积和百分比较高。 ø _α /（O _α + O _β + O _γ）和Ce ³⁺ /（Ce的³⁺  + Ce的⁴⁺），更容易还原Mn物种，高还原性和更多酸性位点。此外，Mn–Ce–Co / NPAC-7和Mn–Ce–Fe / NPAC-7对SO ₂和H ₂ O中毒表现出特定的抵抗力，并提出了SO ₂失活机理。
