Abstract: Herein are disclosed compositions of matter, processes of manufacture and processes of use of solid state admixtures that include an inorganic base and a sulfide selected from the group consisting of an ammonium sulfide, an alkali metal sulfide, an alkali-earth metal sulfide, transition metal sulfide, and a mixture thereof. The composition can include solid state inorganic bases (e.g., calcium hydroxide and sodium sesquicarbonate) and/or gaseous bases (e.g., ammonia) and, optionally, a support material for one or more of the inorganic base and sulfide. The compositions are useful for capturing environmental contaminants, for example, from the flue gas of a coal fired power plant.

Abstract: Preparing a porous hybrid media includes contacting porous media (e.g., strong base ion-exchange media) with an aqueous solution including aluminum ions to yield a aluminum-ion-containing porous media, contacting the aluminum-ion containing porous media with a reducing agent to impregnate elemental aluminum in the porous media, and oxidizing the elemental aluminum to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. In some cases, a pH of an aqueous mixture including the aluminum-ion-containing porous media may be adjusted to form a floc including aluminum hydroxide, and the aluminum hydroxide-containing porous media may be contacted with a reducing agent to yield a porous hybrid media including aluminum hydr(oxide) impregnated in the porous media. The porous hybrid media may advantageously be prepared at low temperature (e.g., room temperature).

Abstract: A carbon dioxide capture and release method of forming a MOF matrix material including at least one metal-organic-framework crystal that includes at least one metal ion or metal ion cluster coordinated to polydentate organic ligands. The method includes forming a positive moisture swing CO2 host by application of at least a portion of the MOF matrix material to at least a portion of a good, and exposing the good to a feed gas. The method also includes altering the absorption and desorption of CO2 in the CO2 host through a swing absorption/desorption process of moisture content, where an equilibrium pressure of CO2 over the CO2 host is based at least in part on the moisture content. The metal-organic-framework crystal can be UIO-66 including Zr6O4(OH)4(CO2)12 clusters linked by terephthalate acid ligands, and/or Zr6O4(OH)4(CO2)12 clusters linked by amino-terephthalic acid ligands, and/or Zr6O4(OH)4(CO2)12 clusters linked by nitro-terephthalic acid ligands.

Abstract: A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.

Abstract: A solid particulate composition useful in extracting a lithium salt from aqueous solutions, the composition comprising lithium, metal atoms, oxygen atoms, and at least one anionic species (X) selected from halide, nitrate, sulfate, carbonate and bicarbonate, all in a framework structure, wherein said metal atoms are selected from at least one of oxophilic main group metal and oxophilic transition metal atoms, provided that, if the metal atoms comprise aluminum atoms, then at least 10 mol % of said aluminum atoms are substituted with at least one metal atom selected from said at least one oxophilic main group and oxophilic transition metal atoms, other than aluminum, and wherein said lithium is present in said composition in an amount less than a saturated amount in order to permit extraction of lithium salt. Methods for extracting and recovering a lithium salt from an aqueous solution by use of the above-described composition are also described.

Abstract: A process for the preparation of an alumina in the form of beads with a sulphur content in the range 0.001% to 1% by weight and a sodium content in the range 0.001% to 1% by weight with respect to the total mass of said beads is described, said beads being prepared by shaping an alumina gel having a high dispersibility by drop coagulation. The alumina gel is itself prepared using a specific precipitation preparation process in order to obtain at least 40% by weight of alumina with respect to the total quantity of alumina formed at the end of the gel preparation process right from the first precipitation step, the quantity of alumina formed at the end of the first precipitation step possibly even reaching 100%. The invention also concerns the use of alumina beads as a catalyst support in a catalytic reforming process.
