Hg Removal Characteristics of Noncarbon Sorbents in a Fixed-Bed Reactor

This research targeted the development of a low-cost, high-efficiency sorbent for mercury capture in flue gas. Six non-carbon-based carriers and various impregnating substances including NaI, CuCl2, CuBr2, and FeCl3 were investigated in this study. The performances of the prepared sorbents were tested in a bench-scale fixed-bed reactor at 140 °C in N2 atmosphere. Some sorbents demonstrated the mercury capture capabilities similar to that of a commercial active carbon sorbent (Norit Darco LH).
