    摘要： A filtration system that uses a filter to convert wastes in automotive exhausts into carbon nanotubes is disclosed. Metallic salts, such as iron salts, may be mixed with diesel fuel by way of using algal biodiesel to ensure homogenous suspension of the metallic salts in the diesel fuel. The metallic salts form a suitable catalyst to grow carbon nanotubes on a filter placed in the pathway of the diesel combustion exhaust. The filter surface may be composed of iron of similar catalyst. The filter may be placed along the pathway of exhaust streamlines preferably at an angle of more than 5 degrees and less than 15 degrees. The filter is heated to temperatures in the range of 200-1000 degrees Celsius. The filter described in this invention can work in its own or supplement existing filtration systems. The filtration system may produce a material that is commercially valuable, synthesized carbon nanotubes.

    摘要： Developed is high-efficiency synthesis method and apparatus capable of promoting the initial growth of carbon nanostructure by eliminating the initial fluctuation time and rising time in raw gas flow quantity. A high-efficiency synthesis method of carbon nanostructure according to the present invention is a high-efficiency synthesis method of carbon nanostructure, the method comprising: bringing raw material gas and a catalyst into contact with each other under reactive conditions so as to produce a carbon nanostructure, wherein: the initiation of contact of the raw material gas with the catalyst is carried out instantaneously. Reaction conditions such as temperature and raw material gas concentration are set so as to meet those for catalyst growth, and under the reaction conditions, the initiation of contact of raw material gas G with catalyst 6 is carried out instantaneously. Consequently, the initial growth of carbon nanostructure is positively carried out, and the height growth and thickness growth thereof can be effected in high efficiency. Further, high-density growth and short-time high-speed growth can be realized. The catalyst includes any forms of catalyst such as catalyst substrate, catalyst structure, catalyst powders and catalyst pellet. It is especially preferred to employ a system wherein the feed and interruption of the raw material gas G are intermittently controlled by means of an electromagnetic three-way valve 24.
