<p>PROBLEM TO BE SOLVED: To provide a recovery system of a fibrous carbon material capable of efficiently recovering a fibrous carbon material by removing part of a catalyst that is contained as impurities in the fibrous carbon material recovered from synthetic particles having the fibrous carbon material formed on the surface of a catalyst carrier, the catalyst coming off a particulate substrate.SOLUTION: A recovery system comprises an agitation vessel 3 for preparing a first dispersion liquid 5 of synthetic particles 1 having a fibrous carbon material formed on the surface of a catalyst carrier carrying a catalyst containing a metal on a particulate substrate, vibration means for vibrating the first dispersion liquid 5 to separate the fibrous carbon material from the synthetic particles 1 in a dispersion medium, a porous member 8 for letting the first dispersion liquid after vibration application pass therethrough and separating the particulate substrate and most of the catalyst containing a metal from the first dispersion liquid to obtain a second dispersion liquid, a magnetic member 9 for separating the catalyst containing a metal that remains as impurities in the second dispersion liquid.</p> |
