Promotion of ceria for decomposition of ammonia bisulfate over V2O5-MoO3/TiO2 catalyst for selective catalytic reduction

Effects of SO2 on the low temperature selective catalytic reduction of NO by NH3 over CeO2-V2O5-WO3/TiO2 catalysts

“…(NH 4 HSO 4 or (NH 4 ) 2 SO 4 ) [2,3], which deposit on the catalyst surface and the pores [4,5], leading to a decrease in De-NO x activity. At present, low temperature industrial boilers with the exhaust gas below 310°C are barely installed on De-NO x devices.…”

Enhancement of CeO2modified commercial SCR catalyst for synergistic mercury removal from coal combustion flue gas

“…Some literatures also prepared the CeO 2 modied V 2 O 5 -WO 3 (MoO 3 )/TiO 2 to investigate the NO removal activity specically, and the satisfactory NO conversions, sulfurresistance and alkali metal resistance were obtained over the catalysts. [26][27][28] Nevertheless, few literatures have made investigations on the effectiveness of employing CeO 2 to directly modify the commercial SCR catalyst of power plant for synergistic Hg 0 removal so far, which is of great value and close correlation to practical application. Moreover, the present commercial SCR catalyst is not replaceable in the short term, though some researched novel catalysts such as Mn-based, Cubased, noble metal and perovskite structure catalysts displayed considerable Hg 0 removal efficiency in the lab-scale tests.…”

Facile Fabrication of Ce/V‐Modified Multi‐Channel TiO2 Nanotubes and Their Enhanced Selective Catalytic Reduction Performance

“…NH 3 -SCR has been considered as the most efficient technology to eliminate nitrogen oxides(NO x )t om eet the upcomings tringent regulations since NO x is one of the main atmospheric pollutants. [1][2][3][4] Though the V 2 O 5 -WO 3 (MoO 3 )/TiO 2 has been applied as ac ommercial catalystb yv irtue of its high de-NO x efficiency and excellent tolerance to SO 2 poisoning, yet the high and narrow temperature window (300-400 8C) restricts its industrial application in many fields. [5,6] In this regard, it is highly recommendedt od os ome innovations on catalysts' design and identify ac andidate of vanadium-based catalyst.…”
