FLUIDIZED BED REACTOR AND PROCESS FOR PREPARING CARBON NANOSTRUCTURES USING SAME

摘要

The present invention provides a fluidized bed reactor, and a method for manufacturing a carbon nanostructure using the same. The fluidized bed reactor comprises: a reactor body; a distribution plate arranged in the interior of the reactor body; a gas supply pipe for supplying a reactive gas in the manner of upward flow from the bottom toward the top of the distribution plate; a first catalyst supply pipe arranged in the bottom of the reactor body so as to supply a first catalyst; and an unreactive carbon source removal means installed in the interior of the reactor body so as to remove unreactive carbon source. The unreactive carbon source removal means comprises: a catalyst housing where air enters and a second catalyst is accommodated; a second catalyst supply pipe for supplying the second catalyst from the exterior of the reactor to the catalyst housing; and a second catalyst discharge pipe for discharging the second catalyst of the housing to the exterior of the reactor. The fluidized bed reactor in accordance with the present invention enables long-term continuous reaction in the fluidized bed reactor as decreasing formation of the carbon structure in an inner wall of the reactor by removing the unreactive carbon source.
