  • Publication number: 20200385270
    Abstract: A composite comprising a hydroxyapatite and at least one additive which is present during hydroxyapatite synthesis. The additive may be embedded or incorporated into or coated onto the hydroxyapatite. The additive preferably increases the hydroxyapatite porosity, e.g., providing a higher pore volume and/or BET surface area than a hydroxyapatite material without additive. The additive preferably comprises an activated carbon, chitosan, hopcalite, clays, zeolites, sulfur, and/or a metal such as Al, Sn, Ti, Fe, Cu, Zn, Ni, Cu, Zr, La, Ce, in the form of metal, salt, oxide, oxyhydroxide, and/or hydroxide. The hydroxyapatite may be calcium-deficient. The composite is in the form of particles having a D50 of at least 20 ?m, a BET surface area of at least 120 m2/g; and/or a total pore volume of at least 0.3 cm3/g. An adsorbent material comprising a composite or a blend of composite with a hydroxyapatite without additive, and its use for removal of contaminants such as Hg, Se, As, and/or B from an effluent.

  • Patent number: 10814303
    Abstract: A process for producing a calcium phosphate reactant, according to which: in a first step, use is made of a source of calcium and a source of phosphate ions in water, in a molar ratio that is adjusted so as to obtain a Ca/P molar ratio of between 0.5 and 1.6, and the source of calcium is reacted with the phosphate ions at a pH of between 2 and 8, in order to obtain a suspension (A) of calcium phosphate, and in a second step, added to the suspension (A) are an alkaline compound comprising hydroxide ions in order to set a pH of more than 8 and an additional source of calcium in order to obtain a suspension (B) of calcium phosphate reactant having a Ca/P molar ratio of more than 1.6. A calcium phosphate reactant obtainable by such a process.

  • Patent number: 10661226
    Abstract: Process for treating a combustion waste gas stream containing NOx and contaminants such as heavy metals and/or acid gases, e.g., halogens, SOx, comprising: injecting an alkali sorbent, into the waste gas stream; removing some contaminants with the alkali sorbent from the waste gas stream; injecting an ammonia source into the gas stream; injecting a deNOx catalyst into the gas stream at a temperature of 100° C. to preferably not more than 600° C. to reduce with NH3, in the presence of O2, some NOx to N2 and water in the gas stream, wherein the deNOx catalyst comprises copper and/or copper oxide deposited on a porous support comprising at least 60 wt % of a calcium-deficient hydroxyapatite having a Ca/P of less than 1.67. A blend comprising the alkali sorbent and the deNOx catalyst may be formed to inject them together into the waste gas stream. The ammonia source and the deNOx catalyst are preferably injected simultaneously.
