The invention provides methods, equipment and apparatuses for a highly flexible assembly system. The system may include at least one item of mobile equipment, at least one mobile container and at least one manufacturing management system (MMS). Because it is so flexible, the system may allow for efficient simultaneous processing of multiple dissimilar products. The system may also accommodate manufacturing processes requiring hybrid methods.

The present invention relates to a method for continuous production of carbon nanotubes in a nano-agglomerate fluidized bed, which comprises the following steps: loading transition metal compounds on a support, obtaining supported nanosized metal catalysts by reducing or dissociating, catalytically decomposing a carbon-source gas, and growing carbon nanotubes on the catalyst support by chemical vapor deposition of carbon atoms. The carbon nanotubes are 4&#x2dc;100 nm in diameter and 0.5&#x2dc;1000 &#x3bc;m in length. The carbon nanotube agglomerates, ranged between 1&#x2dc;1000 &#x3bc;m, are smoothly fluidized under 0.005 to 2 m/s superficial gas velocity and 20&#x2dc;800 kg/mbed density in the fluidized-bed reactor. The apparatus is simple and easy to operate, has a high reaction rate, and it can be used to produce carbon nanotubes with high degree of crystallization, high purity, and high yield.
