▎ 摘　　要

NOVELTY - The device for simultaneously producing the carbon nano tube and the graphene has a reaction device and a separation device (2). The reaction device has a reaction device main body (1). A liquid copper alloy reaction zone (11) is arranged at the lower part inside the reaction device main body. A separation zone (12) is arranged at the upper part inside the reaction device main body. The lower end of the separation area is communicated with the upper end of the liquid copper alloy reaction area. The diameter of the separation area is smaller than that of the liquid copper alloy reaction area. A gas charging opening is formed in the side wall of the lower part of the liquid copper alloy reaction zone. A solid charging opening is formed in the side wall of the upper part of the liquid copper alloy reaction zone. A dispersing structural member (13) is arranged in the liquid copper alloy reaction zone. A separation structural member (14) is arranged in the separation area. USE - Device for simultaneously producing the carbon nano tube and the graphene. ADVANTAGE - The introduced carbon source forms micro bubbles under the influence of the dispersing structural member. Graphene grows in the copper alloy, and the carbon nano tube grows on the nano metal catalyst. The carbon nano tube prevents the graphene from being combined under the stirring of the structural member and the bubbles. The device can directly produce high-quality carbon nano tubes and graphene, has simple reactor structure, does not need to prepare a template agent for graphene growth, is convenient to control and has low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for simultaneously producing carbon nanotubes and graphene, which involves: adding copper alloy powder into the liquid copper alloy reaction zone through the solid feeding port, so that the filling height of the copper alloy powder is lower than the top end of the dispersing structural member; heating the copper alloy powder in the liquid copper alloy reaction zone to enable the copper alloy powder to form liquid copper alloy at a preset temperature; introducing process gas into the liquid copper alloy through the gas charging opening, where the process gas is dispersed under the action of the dispersing structural part to form small bubbles, the small bubbles generate graphene in the liquid copper alloy, and the process gas comprises a carrier gas and a carbon source; adding metal nano-catalyst particles into a liquid copper alloy reaction zone in which the graphene is generated through the solid charging opening, where the metal nano-catalyst particles are in contact with the carbon source to grow into carbon nanotubes, and the carbon nanotubes prevent the graphene from coalescing under the action of the dispersing structural member and the small bubbles to form a primary carbon product in the liquid copper alloy reaction zone; carrying out the primary carbon product by airflow to enter the separation area along with the increase of the accumulated amount of the primary carbon product, and returning the primary carbon product adhered with the copper alloy powder to the liquid copper alloy reaction area in the separation area under the blocking action of the separation structural member, where the primary carbon product not adhered with the copper alloy powder bypasses the separation structural member under the action of the airflow and enters the separation device through the gas-solid outlet; and carrying out gas-solid separation treatment on the primary carbon product in the separation device through the separator, collecting the gas flowing out of the gas outlet and collecting the carbon product containing the carbon nano tube and the graphene flowing out of the solid outlet.
