Summary: | The present invention is in relation to a process for preparing calcium phosphate-based sulfated adsorbents that capture mercury in gas streams, comprised of the steps of synthesis of the precursors, incorporation of a transition metal, and sulfation of the material. These adsorbents present high efficiency both for removal of low concentrations of mercury, such as in natural gas, and for stabilization of this pollutant. The adsorbents obtained in the invention may be used in the Mercury Removal Units (MRUs) present in natural gas processing plants, which mercury removal units may be located either upstream or downstream of the dehydration and H2S removal units, due to the adsorbents obtained showing resistance to H2S poisoning, and maintaining their performance in the presence of water. |
