摘要

通过分步浸渍法制备了一系列以碱土金属或过渡金属为助剂

低钒含量的V-Mx(SO4)y-W/Ti及V-MxOy-W/Ti催化剂

对负载相同金属离子硫酸盐及氧化物的催化剂性质进行了对比考察。通过选择性催化还原(SCR)反应对催化剂进行活性评价

结果显示

负载某金属硫酸盐比相应氧化物助剂的催化剂活性好。负载钴离子的催化剂具有良好的低温活性

进而对负载钴离子的催化剂进行了抗硫抗水性能测试

并借助XRD、NH3-TPD、H2-TPR、TG、BET对负载不同金属硫酸盐及氧化物助剂的催化剂进行了表征

揭示了活性好的催化剂(如负载CoSO4的催化剂)通常具有较多的表面酸及较好的低温还原能力。

Abstract

Several low-vanadium SCR catalysts with alkaline-earth metal and transition metal sulfate(V-Mx(SO4)y-W/Ti)or oxide(V-MxOy-W/Ti)additives were prepared by the impregnation method and evaluated to investigate the effects of the additives on the denitration performance of the catalysts.The results showed that whatever additive it was

the SCR denitration activity of the catalysts doped with metal sulfates was much higher than that doped with metal oxides.Cobalt additive had higher SCR denitration activity in a wide temperature range and showed also good resistance to the poisoning of SO2 and H2O.Characterized by XRD

NH3-TPD

H2-TPR

TG and BET

the catalysts with higher catalytic activity for denitration at a low temperature

such as V-CoSO4-W/Ti

showed always higher surface acidity and better low-temperature reduction ability.
