Claim 22:
23. An apparatus for synthesizing multiwall carbon nanotubes, the apparatus comprising:
a chamber for depolymerizing high molecular polymeric wastes;
a catalytic reactor in fluid communication with the chamber, wherein the catalytic reactor comprises:
a cylindrical outer casing;
an array of catalytic materials consisting of pre-treated 304 type stainless steel having a chromium content of less than 12%;
a holder assembly configured to hold and support the array of catalytic materials, the holder assembly having an inlet, an outlet and a plurality of apertures provided along the longitudinal surface of the holder assembly;
wherein the array of catalytic materials is arranged in a horizontally stacked manner having a space between any two adjacent catalytic materials sufficient to enable multiwall carbon nanotubes to grow on surfaces of the catalytic materials;
a gas distributor channel connected to the holder assembly; and
a heating element wound around the external wall of the outer casing capable of providing uniform induction heating to the array of catalytic materials within the catalytic reactor.
