  • Patent number: 9960298
    Abstract: A method for the preparation of copper indium gallium diselenide/disulfide (CIGS) nanoparticles utilizes a copper-rich stoichiometry. The copper-rich CIGS nanoparticles are capped with organo-chalcogen ligands, rendering the nanoparticles processable in organic solvents. The nanoparticles may be deposited on a substrate and thermally processed in a chalcogen-rich atmosphere to facilitate conversion of the excess copper to copper selenide or copper sulfide that may act as a sintering flux to promote liquid phase sintering and thus the growth of large grains. The nanoparticles so produced may be used to fabricate CIGS-based photovoltaic devices.

  • Patent number: 9954258
    Abstract: Provided is a method of manufacturing high-purity, high-quality manganese sulfate which can be immediately used for manufacturing a lithium ion secondary battery from manganese sulfate waste liquid of a wasted battery. Since impurities are removed from the manganese sulfate waste liquid by using sulfides causing no secondary contamination in the manganese sulfate waste liquid and the manganese sulfate is manufactured by performing evaporation concentration through heating, the manufacturing method is very environment-friendly and economical. Since the manganese recovering process improving the manufacturing yield of the manganese sulfate and the waste water treatment process capable of recycling the source materials and discharging waste water are integrated, the manufacturing method is very efficient and environment-friendly. The manufacturing method is applied to the recycling industry, and thus, it is possible to obtain effects of preventing environmental pollution and facilitating recycling the resources.

  • Patent number: 9926205
    Abstract: A method for producing antimony trisulfide can inexpensively produce antimony trisulfide that has a relatively low content of lead, arsenic, and crystalline silica (i.e., impurities). The method includes charging a reaction vessel with an antimony trioxide powder and sulfur, and heating the inside of the reaction vessel to react antimony trioxide with sulfur. Since antimony trioxide is obtained by volatilization-oxidation refining, antimony trioxide has a small particle size and a large specific surface area, and exhibits good reactivity, and high-purity antimony trioxide having a low content of impurities (e.g., lead, arsenic, and crystalline silica) is easily available. It is possible to inexpensively produce antimony trisulfide having a low content of impurities by utilizing high-purity antimony trioxide as a raw material.

  • Patent number: 9925491
    Abstract: Waste treatment comprises heating it in a chamber to effect pyrolysis of the waste, introducing oxygen into the chamber to effect combustion of the pyrolyzed waste, and contacting off-gas from the pyrolysis and/or combustion steps with an oxidation catalyst to convert carbon monoxide and hydrocarbons in the off-gas into carbon dioxide and water and with a reduction catalyst to convert nitrous oxides to nitrogen and oxygen. Thus, domestic waste is treated in a batch process using catalytic converters to reduce the level of toxic components before off-gas reaches the atmosphere.

  • Patent number: 9914093
    Abstract: Methods for the heat treatment of a material flow and the cleaning of resulting exhaust gases are disclosed. The material flow may be preheated in a preheating zone, burned in a sintering zone, and cooled in a cooling zone. Exhaust gases of the sintering zone may flow through a preheater and be used for preheating the material flow. The exhaust gases leaving the preheater may be cooled at least partially in a comminuting device in interconnected operation or at least partially in a cooling device in direct operation. Exhaust gases may then be at least partly dedusted in a dust filter. A temperature of the dedusted exhaust gas may then be raised before the exhaust gas is cleaned of pollutants in at least one catalyst. A temperature at which the exhaust gases flow through the catalyst in direct operation may be higher, at least in phases, than a temperature at which the exhaust gases flow through the catalyst in interconnected operation.

  • Patent number: 9902909
    Abstract: Hydroprocessing facilities may operate for extended periods of time before detection of mercury in the inlet facilities, as mercury adsorbs onto the metallic pipelines used to transport the hydrocarbon fluids, e.g., gas, produced waters, from the wells to processing facilities (“flowlines”). Once the pipelines become “saturated” with mercury, mercury will breakthrough and be detected at the inlet facilities. A mercury management/control scheme is disclosed wherein a chemical treatment step using aqueous sulfidic solution is integrated into a progressive pigging plan to clean the pipeline, managing mercury accumulation in the pipeline for a reduced mercury concentration in the fluid exiting the flowlines.
