摘要：
The reaction parameters of H2S conversion, H-2 yield and SO2 selectivity obtained by thermal decomposition of H2S in presence of oxygen have been investigated at different operating conditions such as O-2/H2S molar feed ratio, residence time and reaction temperature. Experimental tests allowed to find the best values of operating parameters able to assure a high H2S conversion and a good hydrogen yield, minimizing the SO2 selectivity. The increase of the O-2 concentration has determined an increase of the H2S conversion and the SO2 selectivity and a slight decrease of H-2 yield. The increase of the temperature in the range 700 - 1,100 degrees C has improved the H2S conversion and H-2 yield, with a reduction of SO2 selectivity from about 30 % to 2 %. At temperature of 1,100 degrees C and O-2/H2S = 0.2 good performances were observed in terms of the H2S conversion (58 %), H-2 yield (24 %) with a lower SO2 selectivity (similar to 2 %).
