  • Patent number: 8034313
    Abstract: In slicing a crystal bar into silicon wafers, an average about 40% of silicon would be loss due to the widths of slicing wires themselves. The fact that the silicon slurry is discarded as sludge or discarded after recovering silicon carbide particles causes a large waste of cost. If the silicon slurry (40% of silicon) could be recovered as the raw material for growing silicon crystal bars, the production cost would be lowered. The recovery method of silicon slurry according to the present invention could effectively obtain silicon raw material after removing impurities, which could recover the raw material used in solar crystals, further capable of increasing the silicon crystal production and lowering the cost.

  • Patent number: 8025861
    Abstract: Titanium oxide (usually titanium dioxide) catalyst support particles are doped for electronic conductivity and formed with surface area-enhancing pores for use, for example, in electro-catalyzed electrodes on proton exchange membrane electrodes in hydrogen/oxygen fuel cells. Suitable compounds of titanium and a dopant are dispersed with pore-forming particles in a liquid medium. The compounds are deposited as a precipitate or sol on the pore-forming particles and heated to transform the deposit into crystals of dopant-containing titanium dioxide. If the heating has not decomposed the pore-forming particles, they are chemically removed from the, now pore-enhanced, the titanium dioxide particles.

  • Patent number: 8022002
    Abstract: Regeneration flue gas streams containing unacceptable levels of CO can be effectively combusted (i.e., for more complete combustion or oxidation of CO to CO2) by contact with a second catalyst undergoing regeneration, for example in a second regenerator. While the second catalyst may also be regenerated by contact with an oxygen-containing gas stream, this second catalyst additionally comprises a noble metal, or is present in combination with a combustion comprising a noble metal. Representative catalysts used in an integrated regeneration process are those used for oxygenate conversion and olefin cracking, both for the purpose of producing light olefins (e.g., ethylene and propylene).

  • Patent number: 8012453
    Abstract: This invention describes a complete sequestration of carbon (CO2 and CO) from coal burning plants. In this process, hydrogen can be generated which in turn permits the reduction in the cost of hydride synthesis. The hydrides store hydrogen for on-board application for automobiles and fuel cells. Hydrogen generation and synthesis of hydrides is accomplished by using an integrated approach in which coal is used as a fuel and carbon is sequestered in the process. The CO and or CO2 produced in coal burning power plants and the heat is used when available for producing hydrogen and hydrides. Carbon is used both as a reactant and as a fuel. Economically hydrogen production cost is comparable to or less than the current price of hydrogen produced from fossil-fuel with the added benefit of carbon sequestration and reducing global warming. Specific processes for synthesizing important hydrogen storage materials, hydrides are described.

  • Patent number: 8012614
    Abstract: A non-aqueous electrolyte battery has a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive electrode has a high-capacity positive electrode portion with a plate area per capacity of smaller than 200 cm2/Ah, and a high-power positive electrode portion with a plate area per capacity of 200 cm2/Ah or larger. The non-aqueous electrolyte battery is advantageous in providing a battery, with use of a single kind of non-aqueous electrolyte battery, which simultaneously satisfies the requirements on high-capacity characteristics capable of performing a long-term continuous discharge, and on high-power characteristics capable of performing a pulse discharge at a large current, without using a hybrid power supply unit which has multiple kinds of batteries and requires a complex control system.
