摘要: CS2 and SO2 appear in industrial processes such as the Claus reaction; however, few studies have focused on both simultaneous reactions. In this study, conversion of into elemental sulfur proceeded efficiently, using a radio-frequency plasma-induced system. The main experimental parameters were follows: feeding concentration SO2, discharge power (P), inlet CS2/SO2 ratio (R), system pressure at room temperature. conversions sensitive to either P or R. When was increased from 15 W 120 W, only 27.3% 66.8% [SO2] = 2% R 1, whereas apparently 26.5% 98.2% when 2 ([CS2] 4%). Interestingly, optimum operating condition observed reach larger for CS2, simultaneously. At 2, stoichiometric C/O is providing oxygen prior sink C atom, resulting CO major gaseous product; selectivity S1 0.989 90...
