Abstract

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.
