The H2S removal capacity of copper loaded on a number of titanosilicate supports was investigated. Copper supported on Engelhard Titanosilicate-2 (Cu-ETS-2) has been found to be a superior H2S scavenger for maintaining H2S levels below 0.5 ppm because of its high cation exchange capacity and copper dispersion. Cu-ETS-2 demonstrated higher utilization at room temperature when compared to fully developed commercial H2S adsorbents. In addition it was found that the adsorption capacity of Cu-ETS-2 is maintained over a wide range of activation temperatures.
