  • Patent number: 7157069
    Abstract: Disclosed is an apparatus for the combustion synthesis of carbon nanotubes characterized with the combustor having an oxidizing agent inlet, a fuel inlet and an inert gas inlet, such that the inverse diffusion flame occurs within the combustor, thereby producing carbon nanotubes without using vacuum, and a method for the combustion synthesis of carbon nanotubes using the same. According to the present invention, it is possible to directly collect samples including carbon nanotubes without oxidation and a substrate may be installed with ease. Moreover, the manufacturing cost can be lowered to a level suitable for mass production so that the carbon nanotube technology can be extended to various applications.

  • Publication number: 20050108925
    Abstract: The present invention relates to a method of reducing air pollutant emissions such as dioxin or mercury from combustion facilities including furnaces and electricity generation equipment. More particularly, the invention relates to a method of reducing the amount of air pollutants such as dioxin or mercury from combustion facilities by inputting the precursor of nano-particles such as titanium dioxide photo-catalyst or reactive potassium iodide into the combustion facilities as a mixture with air or fuel supply of the combustion facilities, thereby allowing nano-particles to be synthesized during the combustion process and such synthesized nano-particles to absorb, decompose and adhere the air pollutants in the combustion facilities.
