    Abstract: A process for the separation of carbon dioxide from gas mixtures is disclosed in which a metal oxide sorbent, which is used to capture and release carbon dioxide, is recycled. The process incorporates the regeneration of the carbon dioxide capture capacity of the metal oxide to maintain a high capture capacity over many cycles. The regeneration involves hydrating the metal oxide and then heating the resulting metal hydroxide under a gas atmosphere that is effective to suppress the dehydration of the hydroxide so that dehydration occurs at an elevated temperature. The regeneration may also be used independently from the carbon dioxide separation process to produce, from a metal hydroxide, a metal oxide having an enhanced resistance to attrition and fragmentation.

  • Publication number: 20120068124
    Abstract: Process for producing nanomaterials such as graphenes, graphene composites, magnesium oxide, magnesium hydroxides and other nanomaterials by high heat vaporization and rapid cooling. In some of the preferred embodiments, the high heat is produced by an oxidation-reduction reaction of carbon dioxide and magnesium as the primary reactants, although additional materials such as reaction catalysts, control agents, or composite materials can be included in the reaction, if desired. The reaction also produces nanomaterials from a variety of other input materials, and by varying the process parameters, the type and morphology of the carbon nanoproducts and other nanoproducts can be controlled. The reaction products include novel nanocrystals of MgO (percilase) and MgAl2O4 (spinels) as well as composites of these nanocrystals with multiple layers of graphene deposited on or intercalated with them.

  • Patent number: 8067494
    Abstract: Magnesium oxide (MgO) compounded into a polymer can subsequently be hydrated in-situ within the polymer to form magnesium hydroxide. In the case of silane-based or peroxide-based crosslinkable resins, the MgO hydration and polymer crosslinking can be done in a single process step, or in sequential steps. In the case of non-crosslinkable compounds, hydration can be carried out after compounding (no crosslinking step). In all cases, steam CV, sauna, or hot water bath are options for hydration. This approach enables preparation of polymer compounds that are flame retarded with metal hydrates yet free of the traditional limitations posed by shelf instability, extrusion scorch, undesired dehydration, and processing temperature limitations posed by metal hydrates.
