    Three solids containing Cu oxides were tested as sorbents for H2S removal from hot gas at 600 °C. The formation of a surface layer of sulphides on pellet exterior affected Cu utilization for the sorbent prepared from Cu oxides alone. This improved for the sorbent prepared by impregnation of zeolite with Cu oxides, although complete utilization of Cu was not achieved. The combination of Cu oxides with SiO2 gave the most efficient sorbent. Oxidation of H2S to SO2 on admission of hot gas to the fixed bed was a common observation for all sorbents. The addition of steam to hot gas suppressed the SO2 formation.
