Abstract null null Adsorption is a superior method for removing and recycling high concentration of mercury from nonferrous metal smelting flue gas, especially adsorbents with good sulfur resistance and large adsorption capacity. In this study, Co and Mn oxide-modified layered ITQ-2 zeolites were designed to capture and recycle elemental mercury (Hg0). The physicochemical characteristics of the adsorbents were characterized using BET, XRD, FESEM, TEM, and XPS, and the results showed that Mn/ITQ-...

Abstract null null Oxidation of sulfite and competitive absorption existed in Na2SO3 solution for simultaneous removal of NOx and SO2, inhibited the long-term high-efficiency when used for practical applications. A matching strategy was developed to solve these problems. Antioxidants combination was used to retard the oxidation of antioxidant and enhance inhibition of S(IV) (tetravalent sulfur) oxidation. Hydroquinone (HQ) and sodium thiosulfate (ST) showed a positive synergistic effect on inhib...

Abstract null null Transition metal sulfides have attracted great interest in nonferrous smelting industries for elemental mercury (Hg0) capture owing to their high activity, low cost and resistance to SO2. However, the major obstacle was the deactivation of active sites in adsorbents after the use or at high temperature. Herein, we fabricated rhombic dodecahedral Cu2S hollow nanocages by using high-quality Cu2O crystals as sacrificial templates. Benefiting from the unique structure and composit...

Abstract null null Gaseous SO3 and mercury in the SO2-rich gas have aroused the complexity of multi-pollutants formation and are difficult for disposal. We here proposed a dry-flue gas purification method to capture these two pollutants above the SO3 boiling points (>180 °C), cutting off the downstream transformation. The selective uptake of SO3 and Hg0 at a high temperature from SO2-rich conditions is a challenge. The alkaline sorbent and chalcogen-based active sites were assembled to realize t...

Abstract Inducing gaseous substances to migrate inward into a solid material is one of the effective methods to improve the interfacial adsorption stability. However, the gaseous mercury (Hg0) adsorption on bulk material, especially mineral sulfides, generally occurred on the outer surface owing to their compact structure, resulting in the low bonding stability. This study prepared porous ZnO@CuS with different shell thickness to investigate mercury adsorption performance and bonding stability. ...

Abstract Fine particles with the size below 1 μm are difficult to be captured with the traditional dust removal devices because of their poor charge capacity and filterability. Using the agglomeration pretreatment can realize the fine particles growth, then facilitating the capture process. In this study, a novel system with the combination of corona discharge and embedded turbulence was put forward. The results showed that the device can agglomerate the smaller particles into bigger ones, and t...

Abstract UiO-66-type metal-organic frameworks (MOF) grafted with organic functionalities (–Br, –NO2 and –NH2) are introduced to investigate the elemental mercury (Hg0) removal from flue gas, and the effect for adding linkers on Hg0 removal is discussed. Results indicated that added functional groups did not alter the original topology of adsorbents, although their size and morphology varied. Adding –NH2 and –NO2 functional groups was detrimental for the thermal stability of UiO-66 except for -Br...
