Abstract: The coupling of low-temperature plasma and catalyst has been widely used in the purification of gas pollutants due to the combination of high reactivity of low-temperature plasma and high selectivity of catalyst. In this work, using γ-Al2O3 as support, several catalysts differing in active component, i.e., Cu/γ-Al2O3、Mn/γ-Al2O3、Ce/γ-Al2O3、Fe/γ-Al2O3、Co/γ-Al2O3, were prepared. Then the conversion of carbonyl sulfur (COS) by the coupling of dielectric barrier discharge (DBD) low-temperature plasma and the catalysts were studied, in which the influences of factors such as COS initial concentration, flow rate, humidity, and oxygen concentration on COS transformation were analyzed. The results showed that Cu/γ-Al2O3+DBD not only exhibited higher conversion efficiency than the coupling of other catalysts with DBD, but also effectively inhibited the generation of by-products (H2S, SO2, O3), thereby yielding elemental sulfur with high selectivity. By adopting an inlet COS concentration of 1 700 mL/m3, a gas flow rate of 200 mL/min, a relative humidity of 25%, an oxygen concentration of 0.3%, and a specific energy density (SED) of 1 954 J/L, the Cu/γ-Al2O3+DBD coupling achieved a 98.9% conversion of COS, with nearly no by-products generated. In addition, it was found that the COS conversion correlated negatively with each single variable of inlet COS concentration, gas flow rate, humidity, and oxygen concentration.
