Afterwards a gas flow containing 5,000 ppm of H2S was passed over the catalyst in gas hour space velocity (GHSV) of 5,000 h−1, temperature of 65 °C, steam volume percent of 20 and O2/H2S ratio equal to 2. The results revealed that the catalyst supported on MWNTs exhibited higher conversion amongst its counterparts. Then effects of GHSV, steam volume percent in the feed, catalyst loading and temperature were investigated on conversion of hydrogen sulfide to elemental sulfur for tungsten sulfide catalyst decorated on MWNTs.
