The invention addresses the problem of providing a recycling rotary kiln that can reduce the percentage of combustible gas contained in waste gas and that can reduce the cost to generate superheated steam. A recycling rotary kiln (1) is characterized by comprising: a superheated steam generating unit (2) that generates superheated steam; a pipe body (3) that can rotate about an axis and that has a heating section (A) in which a combustible gas (10G) is generated from a matrix resin by way of heating carbon fiber reinforced plastic (10) having a matrix resin and carbon fiber while supplying superheated steam and a carbon fiber (10S) is extracted from the carbon fiber reinforced plastic (10); a first combustion chamber (43a) that is disposed outside of the pipe body (3) and that heats the heating section (A) by combusting the gas (10G) introduced from the heating section (A); and a second combustion chamber (43b) that supplies heat for generating the superheated steam by way of combusting the gas (10G) introduced from the first combustion chamber (43a).

PROCESS AND APPARATUS FOR PRODUCING COMPOSITE MATERIAL
A process for efficiently producing a composite material comprising a base and carbon nanotubes (CNTs) deposited on the surface thereof, on the basis of a CVD method. The process comprises: feeding a CNT-supporting base (P) and a carbon-source vapor (V) to the heatable chamber of a cylinder (10), the cylinder (10) having been disposed obliquely so that the cylinder can be rotated on the major axis and one end (10a) of the major axis is located above; and yielding CNTs on the surface of the base. The positions of a CNT-supporting-base introduction part (30) and a carbon-source-vapor supply part (40) are determined so that the CNT-supporting base comes into contact with the carbon-source vapor in a reaction zone (12) disposed in at least some of an upstream-side region within the chamber. Protrusions (20) have been disposed on the inner circumferential wall of the chamber. Due to this, by rotating the cylinder, the CNT-supporting base is moved from the upstream side to the downstream side of the cylinder while repeatedly being caught in and lifted up with the protrusions and falling.
