Several modified adsorbents were developed by impregnating palygorskite (Pal) with the active substances CuCl2, CuBr2, NaBr, sulfur (S), MnO2 and Co3O4, which were used to conduct experiments via a bench-scale fixed-bed reactor system in simulated flue gas for evaluating their elemental mercury removal capacity. In addition, a variety of characterization methods were applied to understand the physicochemical...
The regeneration performance of spent catalyst after mercury removal as well as the involved reaction mechanism was investigated. The effects of restoration with or without O2 and/or HCl, O2 and HCl concentration, regeneration temperature, and heating rate on regeneration performance were studied, respectively. The results suggested that two steps were essential in the regeneration process: (1) releasing...
The Hg0 adsorption and oxidation sites on the CuCl2-MF catalyst as well as the role of atomic Cu and Cl in Hg0 removal were identified by a temperature programmed desorption (TPD) experiment. The reaction mechanism with the participation of O2 and HCl was investigated. The changes in surface chemistry of fresh, spent and in situ pretreated catalyst with O2 and/or HCl were investigated by EPR and XPS...
To remove Hg0 from coal combustion flue gas and eliminate secondary pollution of spent sorbent, a novel magnetic catalyst based on CuCl2 modified magnetospheres from fly ash (CuCl2-MF) was developed. The solubility tests, electron paramagnetic resonance (EPR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and physical property measurement system with vibrating sample magnetometer...
