Preparation of FeCl3 modified wood chips hydrochar for gas phase mercury removal from flue gas

A FeCl₃ modified wood chips hydrochar sorbent (Fe_x-HC) was prepared via hydrothermal carbonization method for removing gas phase elemental mercury from simulated flue gas.The mercury adsorption capability of the Fe_x-HC sorbent was evaluated in a fixed bed system.The characterization of the Fe_x-HC sorbent was implemented to determine its physicochem. properties.Combined with Hg-TPD anal., mercury adsorption mechanism of the Fe_x-HC sorbent was ascertained.Results indicated that the modified hydrochar prepared from co-hydrothermal carbonization of wood chips with FeCl₃ possessed high mercury removal capability at 50-250 °C.Addition of FeCl₃ significantly promoted the mercury capture rate of the hydrochar increasing from 10% to more than 90%.The optimal mass ratio of FeCl₃·6H₂O to wood chips was 1.3:1, and the optimum hydrothermal temperature was 180 °C.With SO₂ existing in flue gas, the modified hydrochar still owned a mercury capture rate of 99.3%, proving it high SO₂ tolerance.The characterization results indicated that hydrothermal treatment and addition of FeCl₃ elevated the sp. surface area of the Fe_1.3-HC sorbent to 269.3 m²/g, constructing an abundant porous structure.The Fe_1.3-HC sorbent surface possessed a considerable amount of Fe³⁺, which can promote mercury adsorption by oxidizing Hg⁰ to Hg²⁺.A large number of chem. adsorbed oxygen (O*) and active C-Cl functional groups were also detected on the Fe_1.3-HC sorbent surface, both of which acted as active sites for mercury adsorption.Combing Hg-TPD and XPS anal., it displayed that Hg⁰ was adsorbed onto the Fe_1.3-HC sorbent in the form of HgO and HgCl₂.

Ultra-low temperature removal of element mercury in coal-fired flue gas by activated carbon

Mercury in the coal-fired flue gas will cause severe damage to CO₂ compression/purification equipment, and it must be seriously treated.Cold oxidation adsorption process (COAP) is a novel approach that has achieved the near-zero emission of major pollutants (SO₂, NO_x) from coal-fired flue gas.In this study, the removal of mercury at ultra-low temperatures (below 0°C) within the scenario of COAP was investigated.As the adsorption temperature decreased (from 150°C to -30°C), the mercury removal efficiency of activated carbon initially increased and then decreased, peaking at -20°C.A direct condensation phenomenon of mercury was discovered at -30°C.The oxidation and adsorption process of NO was greatly accelerated at subzero temperatures, which enhanced mercury removal more effectively than at 150°C.However, the homogeneous oxidation rates of Hg-O₂ and Hg-HCl decreased at low temperaturesThe Hg-TPD experiments confirmed that phys. adsorption state of mercury predominated at low temperatures, with a small amount of condensed mercury also presented.A large amount of sulfate on used AC facilitated the conversion of phys. adsorbed mercury into HgSO₄.This study revealed the performance and mechanisms of mercury removal at ultra-low temperatures, which could provide theor. guidance for the development of high-efficiency mercury removal in COAP technol.

Accelerated proton-coupled electron transfer kinetics of iron phthalocyanine for oxygen reduction via heteropoly blue clusters

作者: Naseem, Faheem ; Niu, Shuwen ; Meng, Lingzhe ; Wei, Wei ; Wei, Zhengyu ; Qin, Xue

Iron phthalocyanine (FePc) with tetracoordinated Fe-N₄ site shows promising activity for catalyzing the oxygen reduction reaction (ORR) in alk. media.However, the consecutive proton-coupled electron transfer (PCET) steps with water as the proton donor and low electronic conductivity of FePc raise the kinetic barriers for device application.Herein, a significant effect of polyoxometalates (POMs) on the ORR kinetics of Fe-N₄ sites via surface coordination of FePc is revealed.POM clusters modulate the interactive steric/electronic environment of Fe-N₄, leading to a low barrier for H₂O cleavage to produce protons along with a high electron transfer rate, thereby accelerating the PCET steps of FePc.With precisely controlled electron charge of POM clusters, the influence and mechanism of heteropoly blue in promoting PCET steps of FePc relative to heteropoly acid are elucidated, and noticeably enhanced ORR activity and reaction current are achieved.These findings highlight the potential of POMs as ligands to optimize dynamics of Fe-N₄ at. sites toward efficient alk. ORR.
