    摘要: Herein is disclosed is an Advancement of Amended Silicates, for use in wet FGD scrubbers to prevent reduction and emission of dissolved mercury from the scrubber liquid, thus preventing increased mercury emissions to the atmosphere. The advancements are 3-fold: (1) a manufacturing process whereby the product slurry particles are created by reaction of metal sulfates with metal sulfide in solution, in the presence of a non-swelling substrate, whereby a combination of metal sulfides deposits on the substrate and forms a reactive metal-sulfide coating; (2) a more reactive Amended Silicate product, produced from the disclosed manufacturing method, whereby the advanced product more effectively captures dissolved mercury and transforms it into a mercuric sulfide compound on the surface of the Amended Silicate product slurry particles; and (3) the disclosed method of utilizing the advanced Amended Silicate product, whereby the product is injected directly into the wet FGD scrubber liquid as a slurry.

    摘要: Disclosed herein is a composite material formed from an inorganic mesoporous, or mesoporous-like, material, including mesoporous silica, mesoporous carbon, mesoporous zinc oxide, bentonite and kaolinite clay that is dispersed throughout a polymeric matrix formed by a crosslinked polymer. The crosslinked polymer has acidic- or basic-residues, wherein the basic residues are formed from a monomeric material with at least one ethylenic bond and an amide functional group (e.g. acrylamide), and the acidic residues are formed from a monomer material with at least one ethylenic bond and a carboxylic acid functional group (e.g. acrylic acid). Said composite material may also optionally have further acidic- or basic-residues grafted onto the inorganic mesoporous material. The resulting composite material may be used to remove acidic or basic impurities from a gas in need thereof and can be easily regenerated.

    摘要: A method for separating undesired components from gas mixtures comprises the following steps of providing a gas mixture containing at least two gaseous components, wherein one component is an undesired component, feeding water to the gas mixture, forming a hydrate of the undesired component and a remaining gas mixture, wherein the hydrate is formed by spraying a combination comprising the water and the gas mixture, and separating the hydrate from the remaining gas mixture.
