  • Patent number: 9844767
    Abstract: Disclosed is a catalyst filter, which includes a catalyst support and a nano metallic catalyst sprayed to a surface of the catalyst support. The catalyst filter uses catalyst slurry prepared by using a particulate catalyst, in which a small amount of nano metallic catalyst exhibiting a catalyst performance is sprayed to a surface of the catalyst support, different from an existing patent technique in which catalyst particles are formed and prepared as a support to consume a large amount of catalyst. Therefore, the specific surface area of the catalyst filter is not smaller than the specific surface area of the nano catalyst particles, and thus the catalyst filter may effectively remove and decompose ultra-low concentration gas-state contaminants in an indoor air.

    Abstract: Disclosed are homoleptic diazabutadiene nickel precursors used for the vapor deposition of nickel-containing films. The precursors have the general formula Ni(R-DAD)2, wherein R-DAD stands for substituted 1,4-diazabuta-1,3-diene ligands. The sole presence of the Ni—N bonds was also considered to avoid too high intrusion of other elements, such as carbon, into the nickel-containing films. The flexibility of the Ni—N bond in terms of film deposition also allows using the molecules for nickel, nickel-nitride, nickel-carbonitride, nickel oxide or any other type of nickel-containing films. The nickel-containing film depositions can be carried out by thermal and/or plasma-enhanced CVD, ALD, and pulse CVD or any other type of depositions methods.

  • Patent number: 8715600
    Abstract: A circulating dry scrubber flue gas desulfurization system is disclosed. Hydrated lime is injected into the flue gas upstream of the CDS vessel. The flue gas then passes through a baghouse, where solids are captured. At least a portion of the solids are recycled. The recycle path runs from the baghouse to a splitter, where the solids are divided between the injection points. No distribution box is needed, which permits lowering the height and/or restructuring the location of many components of the system, reducing costs as well as improving or maintaining removal of combustion byproducts from the flue gas.
