Abstract:
The removal of CS2 by a wire-in-tube pulsed corona reactor was experimentally investigated. The effects of O2 and H2 in Ar gas on the removal of CS2 were examined. It was shown that the removal of CS2 increased with the increase of input pulse voltage. The decomposition of CS2 was improved in the presence of O2 in gas stream and the maximal removal was over 97%. The main gaseous products of CS2 decomposition with the addition of O2 in Ar gas were CO, CO2 COS and SO2, while, with the presence of H2 in Ar gas, the main products of CS2 decomposition were H2S and CH4. It was found that with the co-existence of sorbent Ca(OH)2 in the reactor, the gaseous products of CS2 decomposition (SO2 and H2S) were not detected, showing that the products were absorbed by the sorbent Ca(OH)2. It was also found that the removal of CS2 decreased when there was water vapor in gas stream.
