    摘要： A floating catalyst chemical vapour deposition method for producing nanotubes, the method including: supplying a nanotube-material precursor and a catalyst precursor, heating said precursors and injecting said precursors into a heated reaction chamber containing a process gas; pyrolysing the catalyst precursor within the reaction chamber to produce catalyst particles; and pyrolysing the nanotube-material precursor within the reaction chamber in the presence of the catalyst particles in order to produce nanotubes; wherein the method further comprises controlling the size of the catalyst particles at the point of pyrolysis of the nanotube-material precursor by controlling the operational parameters of the reaction chamber and/or of the precursor supplies. A corresponding system for producing nanotubes is also provided. Further provided is an injector subsystem for attachment to a reaction chamber, the injector subsystem comprising: a first portion having a first set of injection pipes for receiving species for delivery into the reaction chamber; and an interface portion that is removably attachable between the first portion and the reaction chamber in use, the interface portion comprising at least one injection pipe arranged to receive the species provided by the first set of injection pipes and to inject said species into the reaction chamber in use;the injector subsystem being operable in use such that, with the interface portion removed, said first set of injection pipes are operable to individually inject their respective species into the reaction chamber, and with the interface portion attached, a pre-mixing chamber is defined by the interface portion in combination with the first portion, for pre-mixing the species provided by the first set of injection pipes prior to the species entering the at least one injection pipe of the interface portion.

    摘要： Provided is a production apparatus (100) for continuously producing aligned carbon nanotube aggregates on a substrate supporting a catalyst while continuously transferring the substrate. The production apparatus (100) includes gas mixing prevention means (12, 13) for preventing gas present outside a growth furnace (3a) from flowing into the growth furnace (3a). The gas mixing prevention means (12, 13) includes: a seal gas ejection section (12b, 13b) for ejecting a seal gas along opening planes of (i) an opening of the growth furnace (3a) through which opening a catalyst substrate (10) is transferred into the growth furnace (3a) and (ii) an opening of the growth furnace (3a) through which opening the catalyst substrate (10) is transferred out of the growth furnace (3a); and an exhaust section (12a, 13a) for sucking and exhausting the seal gas out of the production apparatus (100), so that the seal gas does not flow into the growth furnace (3a) through the openings of the growth furnace (3a). The production apparatus (100) prevents the outside air from flowing into the production apparatus (100), uniformly controls, within a range suitable to production of CNTs, a concentration distribution(s) and a flow rate distribution(s) of a raw material gas and/or a catalyst activation material on the substrate, and does not disturb gas flow as much as possible in the growth furnace (3a).
