APPARATUS FOR SYNTHESIS OF CARBON-CONTAINING NANOMATERIALS Russian patent published in 2020 - IPC C01B32/15 C01B32/90 B82Y40/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to nanotechnology and can be used for production of composite materials and functional coatings. Plant consists of four units combined into a sealed closed reaction system with additional pressure relief assemblies for emergency cases installed on table 1 with mounting board 2: unit 3 for feeding protective gas carrier and reagents, mixer-evaporator unit 4, reaction furnace unit 5 and heat recovery unit 6. Unit 3 comprises balloon 7 with protective gas and balloon 13 with gaseous hydrocarbon, connected via reduction gears 8 and 14 to gas lines 9 and 15, on which flow control valves 10 and 16 are installed, rotameters for flow rate measurement 11 and 17 and check valves 12 and 15, which prevent change of gas flow direction. Gas lines 9 and 15 are connected to inputs at block 4 end. Unit 3 also comprises tank 19 with liquid hydrocarbon, connected at inlet to main line 9, and at the outlet to pump 20 with flow rate regulator 21, feeding reagent to unit 4, housing 23 of which is made in form of cylinder with heating element 24 and set of fixed blades and is fixed on movable carriage 25, moving along guide 26, arranged on table 1, and gas line 29 connected to safety valve 27 and pressure gauge 28, which outputs are connected to unit 6. Inlet flange 30 is connected with unit 5 made in the form of pipe 31 with multi-tier cartridge 32 with solid catalyst not reacting with carbon in case of carbon nanotubes production, or with titanium powder in case titanium carbide is obtained. Pipe 31 is closed by outlet flange 33, on which temperature sensor 34 with indicator 35 is arranged, which outlet is connected via gas line 36 with unit 6 made in the form of tight tank 37 divided into two parts horizontally by glass filter 38.

EFFECT: invention widens the operating capabilities of the apparatus by obtaining nano-sized titanium carbide or carbon nanotubes without additional changes in its design.
