Abstract: A comparative study between nanotitanate doped with different metals (copper, copper–chromium, and cerium) is executed under gasification conditions in order to investigate their maximum H2S removal ability and their breakthrough behavior. Therefore, the sorbent is placed in a fixed-bed reactor and exposed to the H2S containing gas flow at temperatures ranging from 75 to 950 °C. Online analysis is done by a mass spectrometer. The sorbents are also tested by the offline analytical techniques X-ray diffraction (XRD) and scanning electron microscopy (SEM) after the experiments to provide detailed information about their elemental and crystalline composition. The results indicate Cu-ETS-2 as the most effective H2S-scrubber among the tested sorbents. The lowest H2S concentration in the outlet gas is always achieved in water rich gas. Additionally, the H2S capacity is nearly always higher for the water rich gas than in the hydrogen rich gas.
