Transition metal sulfides have exhibited remarkable advantages in gaseous elemental mercury (Hg0) capture under high SO2 atmosphere, whereas the weak thermal stability significantly inhibits their practical application. Herein, a novel N,N-dimethylformamide (DMF) insertion strategy via crystal growth engineering was developed to successfully enhance Hg0 ability of MoS2 at an elevated temperature for first time. The DMF-inserted possesses edge-enriched structure and expanded interlayer...
The kinetic behavior of arsenic (As) release during coal combustion and pyrolysis in a fluidized bed was investigated by applying an on-line analysis system trace elements flue gas. This system, based on inductively coupled plasma optical emission spectroscopy (ICP-OES), developed to measure concentrations gas quantitatively continuously. Obvious variations concentration were observed pyrolysis, indicating strong influences atmosphere temperature behavior. Kinetic laws governing the...
CeO2-based catalysts have been regarded as potential materials for Hg removal due to high catalytic performance, nontoxicity, and low cost. Density functional theory calculations were performed investigate the mercury oxidation mechanism by HCl over a CeO2 catalyst. The thermodynamic stability analysis suggests that stoichiometric CeO2(111) is most stable surface. protonated surfaces takes place at oxygen partial pressures, chlorinated can stably exist under concentrations. adsorption...
In this study, a novel Hg0 adsorption strategy based on nonthermal plasma and porous carbon was proposed tested. The O2 NO in flue gas were used to activate with auxiliary plasma. significantly increased the functionalities surface, it has negligible effect textural properties of carbon. O2/NO co-doped remove elemental mercury (Hg0). sample functionalized by 4% 200 ppm (balanced N2) for 3 min exhibited superior ability, which could be assigned formation large amount C═O, C–NO, C–NO2. O2, NO,...
Copper sulfide (CuS) has received increasing attention as a promising material in gaseous elemental mercury (Hg0) capture, yet how to enhance its activity at elevated temperature remains great challenge for practical application. Herein, simultaneous improvement the and thermal stability of CuS toward Hg0 capture was successfully achieved first time by controlling crystal growth. with moderate crystallinity degree 68.8% showed disordered structure high up 180 °C. Such can maintain stable...
A combination of experiments and density functional theory (DFT) calculations was employed to investigate the detailed reaction mechanism elemental mercury (Hg0) with H2S over a MnO2 surface. The sorbent prepared by low-temperature sol–gel autocombustion method used capture Hg0 from simulated syngas. experimental results show that possesses superior removal capacity; 85% efficiency is achieved in temperature range 80–200 °C. An appropriate concentration promotes forming active sulfur species...
An overview of the strategies for boosting C 2+ selectivity by manipulating CO*(CO).
A porous carbon was synthesized by the combination of freeze-drying and CO2 activation from starch. Nonthermal plasma employed to quickly produce oxygen functional groups on a surface.

Fourier transform infrared spectroscopy X-ray photoelectron analyses suggested that significantly increased amount promoted evolution unique pore structure proven favorable effective loading. elemental mercury (Hg0) adsorption ability enriched...
The development of a sorbent with large elemental mercury (Hg0) adsorption capacity under high SO2 concentration atmosphere is the key point for emission control from nonferrous smelting (NFS) flue gas. By controlling degree crystallization, oxygen incorporation and disorder engineering were simultaneously realized to improve Hg0 MoS2 nanosheets first time. interlayer spacing oxygen-incorporated reaches up 9.4 Å 6.4 normal nanosheets, which enhances exposure active sites. Oxygen-incorporated...
