Nanosized Cation-Deficient Fe−Ti Spinel: A Novel Magnetic Sorbent for Elemental Mercury Capture from Flue Gas

Abstract

Nonstoichiometric Fe-Ti spinel

MnO supported on Fe–Ti spinel: A novel Mn based low temperature SCR catalyst with a high N2 selectivity

“…TPR profile of 5% Mn-10% Fe/TiO 2 showed four obvious reduction peaks. The peak at 331 o C was assigned to the reduction of highly dispersed MnO x [22], the peak at 417 o C was probably assigned to the reduction of Fe 2 O 3 and Mn 3 O 4 [22], and the reduction peaks above 500 o C was probably attributed to the reduction of FeO to Fe [20]. Fig.…”

“…XRD patterns of Fe-Ti spinel, 10% Mn/Fe-Ti spinel and 5% Mn-10% Fe/TiO 2 were shown in [20]. After the loading of MnO x , no additional characteristic reflections corresponding to crystalline manganese oxides appeared (shown in Fig.…”

“…Fe-Ti spinel was prepared using a co-precipitation method followed by the thermal treatment under air for 3 h at 500 o C [20,21]. 10% Mn/Fe-Ti spinel was prepared by the conventional impregnation method using manganese nitrate as precursor and Fe-Ti spinel as support.…”

A novel dual layer SCR catalyst with a broad temperature window for the control of NO emission from diesel bus

“…Both Fe-Ti spinel (Fe:Ti = 2:1) and Mn-Fe spinel (Fe:Mn = 5:1) were synthesized using a co-precipitation method [10,11]. The solution with suitable amounts of ferrous sulfate, ferric chloride, and manganese sulfate/titanium tetrachloride was added to an ammonia solution with 800 rpm of stirring.…”

Oxidation Catalysts for Elemental Mercury in Flue Gases—A Review

“…Kong et al [34] Mn-Fe spinels [32,65] and nanosized cation-deficient Fe-Ti spinels [66,67] were presented as effective materials for Hg el capture in the absence of HCl. The Hg el sorption capacity of Mn-Fe spinels was promoted by higher Mn contents.…”
