Characterization of copper supported on titanosilicates for room temperature H2S adsorption

  • Hydrogen sulfide (H2S) is a major contaminant of industrial gas streams. Amongst the various methods used for its removal, adsorption by metal oxides is the most promising. Copper oxide (CuO) is shown to have superior H2S removal capability at room temperature. H2S removal at room temperature is useful when the gas stream’s temperature is low and in applications such as on-board fuel processing of proton exchange membrane fuel cells. The addition of supports improves the adsorption capacity and utilization of copper species. In this study, Engelhard titanosilicates (ETS-2, ETS-4 and ETS- 10) were chosen as supports due to their high surface area and ion-exchange capacities. Copper species were dispersed on the supports via ion-exchange. The H2S adsorption potential of Cu-ETS-2, Cu-ETS-4 and Cu-ETS-10 versus commercial H2S scrubbers was investigated. Cu-ETS-2 was found to be the most effective adsorbent at room temperature due to its high external surface area and high dispersion of copper species.
