    摘要： Provided are a carbon nanotube production device and production method capable of realizing high-temperature heating of a catalyst raw material in a floating catalyst chemical vapor deposition (FCCVD) method, and improving the quality and yield of carbon nanotubes synthesized. A carbon nanotube production device 1 includes a synthesis furnace 2 for synthesizing carbon nanotubes; a catalyst raw material supplying nozzle 3 for supplying a catalyst raw material used to synthesize carbon nanotubes to the synthesis furnace 2; and a nozzle temperature adjusting unit 6 capable of setting a temperature of an inner portion 4 of the catalyst raw material supplying nozzle 3 higher than a temperature of a reaction field 5 of the synthesis furnace 2. By supplying to the synthesis furnace 2 the catalyst raw material that has been thermally decomposed after being heated to a temperate at which a catalyst metal will not yet be condensed, and by having the thermally decomposed catalyst raw material rapidly cooled to a CVD temperature at the synthesis furnace 2, microscopic catalyst metal particles will be generated at a high density in the space of the reaction field 5 such that carbon nanotubes having a small diameter can be vapor-grown at a high density.

    摘要： Aqueous effluent treatment system including a separation reactor having a reactor chamber fluidly connected to an aqueous effluent source, connected via a pump to an inlet of the reactor chamber, a fluid extraction system connected to a liquid effluent outlet at a top of the reactor chamber, and a solid residue extraction system connected to a solid residue outlet at a bottom of the reactor chamber. The separation reactor is operable to generate pressures exceeding 22 MPa and temperatures exceeding 300° C. in the reactor chamber configured to generate a supercritical zone in an upper portion of the reactor chamber to which the liquid effluent outlet is connected, and a subcritical zone in a lower portion of the chamber within the reactor chamber to which the solid residue outlet is connected. The solid residue extraction system comprises an output circuit comprising a collector coupled to the solid residue outlet via a collector input valve (V1) and to a water output tank via a filter and a collector liquid output valve (V4) operable to be opened to cause a pressure drop at the solid residue outlet to draw solid residue out of the reactor chamber, the solid residue extraction system further comprising a gas feed circuit connected via a gas supply valve (V5) to the collector, the gas supply valve operable to be opened to extract solid residues in the collector to a solids output tank connected to the collector via a collector solids output valve (V6).

    摘要： The invention relates to a device for the thermal or thermo-chemical treatment, more particularly calcination, of material (12), more particularly battery cathode material (14), comprising a housing (16), in which a process space (20) is located. The material (12), or carrying structures (40) loaded with the material (12), can be conveyed in a conveying direction (30) into or through the process space (20) by means of a conveying system (28). A process space atmosphere (50) prevailing in the process space (20) can be heated by means of a heating system (48). There is a process gas system (64), by means of which a process gas (66) can be fed to the process space (20), said process gas being required for the thermal treatment of the material (12). The process gas system (64) comprises a plurality of local injection units (68), which are arranged and configured such that process gas (66) can be released in a targeted manner onto the material (12) or onto the carrying structures (40) loaded with material (12), the process gas being released in a plurality of local process gas streams (70), each having a main stream direction (72). The invention also specifies a method for the thermal or thermo-chemical treatment of material (12), in which process gas (66) is released in a targeted manner onto the material (12) or onto the carrying structures (40) loaded with material (12), the process gas being released in a plurality of local process gas streams (70), each having a main stream direction (72).
