Method for synthesis of carbon nanostructure material by using organic material

Abstract

The invention discloses a method for synthesis of a carbon nanostructure material by using an organic material. According to the method, a solid organic waste material is subjected to thermal cracking to obtain one or more gaseous carbon-containing monomers of the organic waste material; combustion-supporting gas is added to carry out complete mixing combustion to generate mixed gas containing carbon dioxide, carbon monoxide and hydrogen; after a high temperature filtration treatment is performed, the treated mixed gas is introduced into a tube type furnace to be converted into the carbon nanostructure material, and the high heat value combustible gas generated during the reaction process is collected as a by-product. With the technical scheme, the thermal cracking treatment is adopted to decompose the solid organic waste with the organic polymer form into the solid organic waste with the organic monomer form, such that the carbon source in the organic monomer is synthesized into the carbon nanostructure material under the effect of the catalyst; the preparation method is simple, the synthetic steps and the process are easy to control, the raw materials adopted by synthesis are sufficient, and the cost is low; concurrently the by-product generated during the synthesis process is the combustible gas with the high heat value, and the combustible gas can be recovered as the supplement for energy consumption during the reaction process.
