Adsorption and oxidation of SO2 in a fixed-bed reactor using activated carbon produced from oxytetracycline bacterial residue and impregnated with copper
The SO2 removal ability (including adsorption and oxidation ability) of activated carbon produced from oxytetracycline bacterial residue and impregnated with copper was investigated. The activated carbon produced from oxytetracycline bacterial residue and modified with copper was characterized by x-ray diffraction, scanning electron microscopy, and energy-dispersive spectroscopy. The effects of the catalysts, SO2 concentration, weight hourly space velocity, and temperature on the SO2 adsorption and oxidation activity were evaluated. Activated carbon produced from oxytetracycline bacterial residue and used as catalyst supports for copper oxide catalysts provided high catalytic activity for the adsorbing and oxidizing of SO2 from flue gases.
Implications: To improve the SO2 removal efficiency and reduce costs, the pretreatment of activated carbon or activated carbon-based materials has been widely studied. Oxytetracycline bacterial residue is currently a hazardous waste, which has been investigated in terms of an adduct to active carbon (OBR-AC). Unfortunately, the application of OBR-AC was limited due to the absence of several metals in it, such as Fe and K. The OBR-AC was loaded with copper by immersion method to prepared Cu/OBR-AC, which was used to absorb and oxidize SO2. Cu/OBR-AC exhibited significantly greater catalytic activity than OBR-AC.
