Embodiment 1

[0032] Set the temperature in the high-temperature cracking furnace to 300°C, place the quartz tube in the furnace, and feed 5 liters of argon (or carbon dioxide) per minute into the tube as an inert gas. Cut 1 gram of waste plastic bottle caps made of polypropylene into strips of 20×60 mm, place them in a quartz tube, and pyrolyze them in an oxygen-isolated environment.

[0033] Solid high-density polypropylene undergoes pyrolysis and is completely decomposed into a mixture of gaseous hydrocarbons with high calorific value, the main components of which are methane, ethane, ethylene, propane, propylene and acetylene. After the mixture is fully mixed with one or more mixed gases of oxygen, nitrogen, argon, carbon dioxide, and water vapor in the venturi tube at the end of the quartz tube, it is automatically ignited at high temperature to produce 12% carbon dioxide, 20% carbon monoxide and 8% hydrogen.

[0038] Set the temperature in the high-temperature cracking furnace to 600 °C, place the quartz tube in the furnace, and feed 3 liters of argon (or carbon dioxide) per minute into the tube as an inert gas. 4 grams of bagasse fibers were crushed into particles with a size below 500 microns and placed in a quartz tube to be pyrolyzed in an oxygen-free environment.

[0039] The solid bagasse fiber is pyrolyzed and completely decomposed into a mixture of gaseous hydrocarbons with high calorific value, the main components of which are carbon monoxide, methane, ethylene, ethane and acetylene. One or more mixed gases of hydrogen, nitrogen, argon, carbon dioxide, and water vapor are introduced into the Venturi tube to fully dilute the pyrolysis gas, and then lead it into a filter, and the introduced gas Filtration is performed to obtain reaction gas for synthesizing carbon nanomaterials.

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.
