摘要

Mn-Ce based catalysts doped with transition metal were synthesized via a sol-gel method for low-temperature Selective catalytic reduction DeNOx. NOx conversion of these catalysts was evaluated under 100 °C -300 °C. H2-Temperature Programmed Reduction was used to investigate the reduction capability effect on NOx conversion. On this basis, sulfur resistance of catalysts was analyzed and Fourier Transform Infrared (FI-IR) spectra were used to discuss sulfur poisoning mechanism of catalysts. The results indicated that NOx conversion of catalysts was Mn-Ce-W0.03 ≈ Mn-Ce-Y0.03 > Mn-Ce-Zr0.03 > Mn-Ce >Mn-Ce-La0.03 > Mn-Ce-Pr0.03.W, Zr, Y elements was doped to improve catalytic activity at low-temperature and enhance anti-sulfur ability of catalysts. Especially, W element can restrain sulfate formation and reduce the channel blocking of the catalyst and Mn-Ce-W0.03 catalyst displays optimal performance of resistance to sulfur poisoning.
