Organic sulphur compounds present in coal gas containing 15‐20% CO were effectively converted into H 2 S over a “Nimox” (nickel‐molybdenum) conversion catalyst. H 2 S was effectively removed by “Luxmasse”, a prepared iron oxide. The overall removal of organic sulphur depended upon the concentration of thiophene present. With only 10 ppm thiophene in the gas, the conversion of organic sulphur was 97% at 350°C after a single treatment. With six‐stage treatment at 350 psig, the final gas contained only 0.2 ppm total organic sulphur in the presence of 4‐5% water vapor.
