Removing Chlorobenzene via the Synergistic Effects of Adsorption and Catalytic Oxidation over Activated Carbon Fiber Loaded with Transition Metal Oxides

This study focused on the elimination of chlorobenzene by dual adsorption/catalytic oxidation over activated carbon fibers (ACFs) loaded with transition metal oxides (TMOs). The TMOs were successfully ACFs incipient wetness impregnation method, which has advantages easy preparation, low cost, and size uniformity. removal effects for (CB) investigated pristine TMOs@ACFs in a fix-bed reactor. experiments result demonstrated that can be used as very efficient adsorbent low-concentration CB at temperature 120 °C; breakthrough time reach 15 h an inlet concentration 5000 ppmv space velocity 20,000 h−1. As bed rose above 175 °C, mainly contributed to catalytic MnO2; preferable ratio was achieved higher temperatures presence more MnO2. Therefore, effectively removed adsorbent/catalyst MnO2@ACF full range below 300 °C.
