  • Patent number: 12017199
    Abstract: 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.

  • Patent number: 11980870
    Abstract: A solid-supported Pd catalyst is suitable for C—C bond formation, e.g., via Suzuki-Miyaura and Mizoroki-Heck cross-coupling reactions, with a support that is reusable, cost-efficient, regioselective, and naturally available. Such catalysts may contain Pd nanoparticles on jute plant sticks (GS), i.e., Pd@GS, and may be formed by reducing, e.g., K2PdCl4 with NaBH4 in water, and then used this as a “dip catalyst.” The dip catalyst can catalyze Suzuki-Miyaura and Mizoroki-Heck cross coupling-reactions in water. The catalysts may have a homogeneous distribution of Pd nanoparticles with average dimensions, e.g., within a range of 7 to 10 nm on the solid support. Suzuki-Miyaura cross-coupling reactions may achieve conversions of, e.g., 97% with TOFs around 4692 h?1, Mizoroki-Heck reactions with conversions of, e.g., a 98% and TOFs of 237 h?1, while the same catalyst sample may be used for 7 consecutive cycles, i.e., without addition of any fresh catalyst.
