Abstract：

ZnFe2O4/AC　composites　were　prepared　by　the　one-pot　hydrothermal　method　using　the　activated　carbon　(AC)　as　a　carrier.　The　synthesis　conditions　were　optimized　by　a　single-factor　experiment.　The　structural,　textural,　and　surface　properties　of　the　adsorbent　have　been　comprehensively　characterized　by　scanning　electron　microscopy　(SEM),　X-ray　diffraction　(XRD),　Fourier-transform　infrared　(FT-IR)　spectroscopy,　Brunauer-Emmett-Teller　(BET)　measurements,　and　X-ray　photoelectron　spectroscopy　(XPS)　analysis.　The　SO2　removal　capacities　of　the　composites　were　investigated　via　testing　the　adsorption　capacity　at　the　self-made　desulfurization　equipment.　The　results　show　that　the　adsorption　capacity　of　ZnFe2O4/AC　composites　is　much　higher　than　that　of　the　AC　and　ZnFe2O4　samples,　respectively.　The　composite　overcomes　the　disadvantages　of　the　traditional　sintering,　showing　a　very　high　desulfurization　performance.　The　breakthrough　time　was　147　min,　and　the　sulfur　adsorption　capacity　could　reach　23.67%　in　the　desulfurization　performance　test.　©　2018　Hui-qiang　Wang　et　al.
