Porous carbon-based sorbents are considered as one of the most promising materials for solving atmospheric mercury pollution. In this study, a novel porous carbon-based sorbents ZnS/AC were prepared from high sulfur petroleum coke (HSPC) and zinc nitrate by in-situ method. The as-prepared ZnS/AC sorbents were characterized by BET, XRD, ICP-OES and XPS analyses, and the element mercury removal performance of these sorbents from the simulated coal derived fuel gas were evaluated using a bench-scale fixed-bed reactor. The effects of atmospheres and temperatures on the Hg-0 removal performance of ZnS/AC sorbents were also studied. The mercury removal efficiency could maintain above 84% within 4 h at <= 120 degrees C under N-2 + H-2 + H2S atmospheres. The higher temperature was not conducive to mercury removal. The average mercury removal efficiency was only 30% within 2 h at 180 degrees C. Hydrogen sulfide (H2S) significantly improved the mercury removal performance of the ZnS/AC sorbent, while the concentration of H 2 S hardly affected the mercury removal efficiency. The mercury removal efficiency of the regenerated ZnS/AC sorbents after mercury capture still maintained above 85% within 6 h at 120 degrees C after three cycles of capture-regeneration, it can be concluded that ZnS/AC sorbent is a promising and efficient sorbent for removing elemental mercury from fuel gases.
