Abstract
In a production system for vapor-grown carbon nanofibers includes a static mixer and a micro mist nozzle for preventing un-uniform input material from forming impurities, an anti-adhering coating covering an inner wall of a vertical tubular reactor for preventing a catalyst, raw material and carbon fibers from adhering to the inner wall of the vertical tubular reactor, and a sedimentation device into which a dispersant and water are inputted to separate produced carbon fiber compositions from particulate impurities in water.
Claims4
A production system for vapor-grown carbon nanofibers, the production system comprising:
- a vertical tubular reactor having a reaction gas inlet, a carrier gas inlet and a product outlet, wherein the reaction gas inlet and the carrier gas inlet are located on a top of the vertical tubular reactor, and the product outlet is located at a bottom of the vertical tubular reactor;
- an anti-adhering coating covering an inner wall of the vertical tubular reactor;
- a heater disposed adjacent to an outer wall of the vertical tubular reactor;
- a sedimentation device, comprising:
- a product catching portion connected and communicating with the vertical tubular reactor, the product catching portion having a dispersant and water inlet, and a fiber suspension outlet;
- and
- a tapered portion connected and communicating with the product catching portion;
- a fiber suspension collecting device connected to the fiber suspension outlet;
- a centrifuge connected to the fiber suspension collecting device, the centrifuge having a wet fiber outlet;
- a dryer connected to the wet fiber outlet, the dryer having a dry fiber outlet;
- and
- a graphitization furnace connected to the dryer fiber outlet.
