The enhancement of CuO modified V2O5-WO3/TiO2 based SCR catalyst for Hg° oxidation in simulated flue gas

Enhanced activity and SO2 resistance of Co‐modified CeO2‐TiO2 catalyst prepared by facile co‐precipitation for elemental mercury removal in flue gas

“…This might be attributed to the well dispersion of CeO 2 and Co 3 O 4 on catalyst surface due to the addition of appropriate amount of Co into the catalyst, as shown by XRD and Raman results. While a decrease of surface area was observed with the addition of excessive Co species, possibly owing to the resultant particle aggregation and pore blockage . The surface area of CeCo 8 /Ti was lower than that of Ce/Ti, but it exhibited better performance on Hg 0 removal, indicating that the physical characteristics might not be the main contributor for catalyst activity.…”

“…Up to present, several methods have been proposed for the mercury abatement from flue gas, such as sorbent injection, photochemical oxidation, electro‐catalytic oxidation and catalytic oxidation . Modified active carbons (sulfur/halogen/metal oxides modified) can effectively remove elemental mercury from flue gas, but the high operation cost and complex separation progress from ultrafine fly ash hinders its application.…”

“…A variety of transition metal oxide catalysts for mercury oxidation, such as Mn, Cu, Fe, V, Ce and Co, have been employed in experiments. Ce‐based catalyst is regarded as one of the best candidates for Hg 0 oxidation removal with O 2 as the oxidant due to its active and facile Ce 3+ /Ce 4+ redox cycle and the corresponding outstanding oxygen storage capacity .…”

Review on the latest developments in modified vanadium-titanium-based SCR catalysts

“…According to previous studies, modification by transition metals (Fe [149] , Cu [150], Ag [151] , Ru [152,153] , Ce [154][155][156], etc. ), metal chlorides (CaCl2 [157], CuCl2 [158], etc.…”

Promoting Effect of the Core-Shell Structure of MnO2@TiO2 Nanorods on SO2 Resistance in Hg0 Removal Process

“…Oxides, such as CuO x [7,8], FeO x [9,10], CeO x [11,12] and MnO x [13][14][15], with high redox properties, exhibit great potential for Hg 0 adsorption. Among these oxides, MnO x is a commonly available and inexpensive material has received extensive attention due to the redox couples of Mn 2+ /Mn 3+ and Mn 3+ /Mn 4+ [16].…”
