  • Patent number: 8043592
    Abstract: In a series of reactions for power plant energy generation designed to make beneficial use of oil bearing sands, oil bearing shale and other starting materials containing silicon dioxide, the silicon dioxide starting materials are combined with a primary energy provider containing hydrocarbon to start a first reaction. During this first reaction, the silicon dioxide containing starting material is heated and crystalline silicon is produced. Then, the crystalline silicon is used in a second reaction which runs exothermically (i.e., releases heat). The heat produced from the second reaction is employed as a secondary energy to supplement the primary energy provider when heating the starting material in the first reaction and/or to supply at least one further reaction or series of reactions with the required energy, at the end of which a silicon compound is produced.

  • Publication number: 20110123428
    Abstract: A method and a system for producing calcium carbide, the method including mixing powdery carbon-containing raw material with powdery calcium-containing raw material, and directly heating the mixture by combusting a part of carbon-containing raw material in an oxygen-containing atmosphere to produce calcium carbide. The carbon-containing raw material can be coal, semi-coke or coke, the calcium-containing raw material can be calcium carbonate, calcium oxide, calcium hydroxide or carbide slag. The system includes a raw material preheating unit, such as a fluidized bed or an entrained flow bed, and a reaction unit such as an entrained flow bed. By combustion of the by-product CO produced during the production of calcium carbide or auxiliary fuel in the air to preheat the raw materials to 500-1500° C., the carbon consumption and the oxygen consumption for the calcium carbide production can be reduced, and thus process energy consumption is further reduced.

  • Patent number: 6261712
    Abstract: Disclosed is a method of reclaiming a cathodic active material of lithium ion secondary batteries. The lithium ion secondary battery is broken and the casing and the content are separated to remove the casing from the content. The content is dissolved into a mineral acid to separate remaining non-dissolved content from the mineral acid to obtain a liquid containing the cathodic active material represented by the formula: LiMO2, where M is a transition metal element: cobalt, nickel and manganese. A lithium salt is added to the liquid, and the cathodic active material is recovered from the liquid in the form of a mixture of lithium compound and the transition metal compound, which is calcined and reclaimed into the cathodic active material.

  • Patent number: 4594236
    Abstract: Calcium carbide is prepared from a powdered lime material. The powdered lime material, possibly together with a reducing agent, is injected with the aid of a carrier gas into a plasma gas generated by a plasma generator. The heated lime material, together with any reducing agent used and the energy-rich plasma gas, is then introduced into a reaction chamber substantially surrounded on all sides by a solid reducing agent in piece form. When the lime material consists of quicklime, this is melted and reduced to liquid carbide and when the lime material consists of powdered limestone, it is burnt directly in the reaction zone to form liquid carbide.
