An improved reactor vessel for processing (recycling and upcycling) of plastics includes a shear plate assembly disposed on a rotatable shaft concentrically disposed within a cylindrical reactor vessel. The shear plates are spaced from the vessel wall to generate a predetermined strain rate between the shear plate and the inner wall via Couette flow, enhancing efficiency of the reaction.

A horizontal pyrolysis furnace has a kiln and two barrels. The two barrels are respectively a processing barrel rotatably disposed in the kiln and a takeover barrel detachably connected with the processing barrel. Each one of the two barrels has a gate assembly and at least one spiral guiding plate. The gate assembly of the processing barrel is mounted on an end of the processing barrel, and extends out from the kiln. The two gate assemblies of the two barrels are detachably connected such that the two barrels are able to rotate synchronously. The at least one spiral guiding plate is fixed on an inner surface of one of the two barrels, and the spiral guiding plates of both barrels have an identical helical direction.

The invention relates to a installation (4) for recycling composite materials comprising a horizontal reactor (5) with a first zone (1), second zone (2) and third zone (3), which are leak-tight and independent, aligned with and separated from one another by means of gates that allow the passage of the composite material to be recycled only when the process has ended in a previous zone. The first zone (1) comprises a rotation mechanism (9) for rotating the material and gas outlet means (8). The second zone (2) comprises air injectors (10) and gas outlet means (11). The third zone (3) comprises cooling means. The invention also relates to a method for recycling composite materials comprising a first pyrolysis phase, a second gassing phase for gassing the material resulting from the first phase, and a third cooling phase for cooling the reinforcement material.
