have determined the Hg removal capacities of Pt and Pd supported on alumina at a range of different metal loadings from 2 to 9 wt%,, using Hg vapour in a simulated fuel gas feed. In the temperature range studied (204-388 degrees C) Pd proved far superior to Pt for Hg removal. The Hg removal capacity for both Pt and Pd increased with metal loading, though decreased with sorbent temperature. A shift in the 20 position of the Pd XRD diffraction peak from 82.1 to 79.5 after Hg adsorption at 204 degrees C was consistent with the formation of a solid solution of fig in Pd.
