; 文献标志码:A 文章编号:1672-7207(2015)06-2382-09 Sodium poisoning mechanism and regeneration of commercial De-NOx SCR catalysts GAO Fengyu, TANG Xiaolong... poisoning of commercial De-NOx SCR catalysts (V2O5-WO3/TiO2) and the regeneration of deactivated catalysts by water and 0.5 mol/L H2SO4 were studied under simulated condition in laboratory......
catalysts were prepared by impregnation. The modification of Sm2O3 for Ni/sepiolite was investigated by TPR, XPS and poisoning of CS2, respectively. The results indicate that the addition of Sm2O3 improves the activity of hydrogenation and anti-poisoning ability of Ni/sepiolite catalyst, and it also increases the dispersion of nickel atoms over support and the amount of active nickel atoms in catalyst......
and tensile properties of B-refined and Sr-modified Al-11Si-1.5Cu-0.3Mg casting alloys were investigated. With a trace addition of La(0.05wt%-0.1wt%), the mutual poisoning effect between B and Sr can......
that the columnar dendrites structure is observed with high content of Sr, indicating a poisoning effect of the Al-5Ti-B grain refinement. In addition, Sr intermetallic compounds distribute on the TiB2 particles, which agglomerate inside the eutectic Si. The mechanism responsible for such poisoning was discussed. The addition of Mn changes the morphology of iron intermetallic compounds from β-Al5FeSi......
