  • Publication number: 20160138131
    Abstract: The disclosure describes a method of separating and recovering valuable metals from remanufacturing solution of a spent desulfurization catalyst containing vanadium, and more particularly, to a method of separating and recovering a valuable metal from remanufacturing solution of a spent desulfurization catalyst containing vanadium, which includes: adding organic acid to a spent hydrodesulfurization catalyst after collecting the spent hydrodesulfurization catalyst in order to prepare the remanufacturing solution of the spent hydrodesulfurization catalyst; adding an extracting agent and a diluent to the remanufacturing solution to extract molybdenum and extracting vanadium from an extracted filtrate to obtain an organic phase; and adding a stripping agent to the organic phase to strip and recover vanadium.

  • Publication number: 20100310740
    Abstract: Provided are a composition for the ketogenic diet and a preparation method thereof, specifically a composition suitable for the ketogenic diet provided in a liquid form, which has the ketogenic ratio of 3-5:1, and a preparation method thereof. The composition for the ketogenic diet according to the preparation method of the present invention can be easily taken by patients since it does not cause rejections such as vomit or diarrhea which may occur with the start of the ketogenic diet, and eliminate the inconvenience of taking additional food for obtaining other functional elements required for the human body owing to functional substances included therein. Moreover, the homogenous liquid form of the present composition allows it to easily slide down the throat and provides good texture in the mouth, thereby it helps a patient to easily take the same.

  • Patent number: 6406646
    Abstract: A resistive paste composition comprising 5 to 75% by weight of ruthenium(Ru) metal or ruthemium oxide particles having a specific surface area of 5 to 30 m2/g, 5 to 75% by weight of silver(Ag) metal or its compound particles having an average particle size of 0.1 to 3 &mgr;m and a maximum particle size of 8 &mgr;m or less, 5 to 40% by weight of a glass frit having a softening point of 400 to 550° C. and 5 to 45% by weight of an organic binder can be coated by a conventional screen-printing or dipping method on a substrate and then calcined at a low temperature of about 500 to 600° C. to form an electrically heat-generating thick film layer having good stability, uniformity and heat-up characteristics.
