  • Publication number: 20230023192
    Abstract: Described herein is a an adsorbent and/or absorbent composition, a method of preparing the adsorbent and/or absorbent composition, and method of treating a fluid stream with the adsorbent and/or absorbent composition. Alumina and carbon are combined with polyacrylamide (PAM) powder and water in preferred proportions and impregnates such as Group 1A metal hydroxides. Group 7A salts of Group 1A metals optionally can be added.

  • Patent number: 11066426
    Abstract: Disclosed herein is a method of making a porous molecular structure from a solution comprising an insoluble metal containing material and a ligand-providing material. In some embodiments, the porous molecular structure can be a Metal-Organic Framework (MOF). Ionic metal salts are the most common type of metal source for MOF production, but dissolution of metal salts complicates solvent recycling and creates corrosion and oxidation issues through evolved nitrate and chloride anions. Elucidating information that leads toward more efficient production of these versatile nanomaterials, while extending the knowledge base of how MOFs form during reaction, is critical to advancing MOF materials into large-scale use. Disclosed herein are improved methods for controlled synthesis of porous molecular structures such as MOFs comprising a solution-based synthesis with insoluble metallic precursor.
