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 reactor for coating particles includes one or more motors, a rotary vacuum chamber configured to hold particles to be coated, wherein the rotary vacuum chamber is coupled to the motors, a controller configured to cause the motors to rotate the rotary vacuum chamber about an axial axis of the rotary vacuum chamber such that the particles undergo tumbling agitation, a vacuum port to exhaust gas from the rotary vacuum chamber, a paddle assembly including a rotatable drive shaft extending through the rotary vacuum chamber and coupled to the motors and at least one paddle extending radially from the drive shaft, such that rotation of the drive shaft by the motors orbits the paddle about the drive shaft in a second direction, and a chemical delivery system including a gas outlet on the paddle configured inject process gas into the particles.

The present disclosure relates to a rotating liquid film reactor with gas-liquid concurrent and use thereof in preparation of metal hydroxides. The present disclosure starts from the basic process of preparing metal hydroxides by a gas-liquid precipitation method, and designs a rotating liquid film reactor with gas-liquid multi-fluid concurrent through computational fluid dynamics simulation analysis. Multiple gas-liquid fluid inlets are constructed, and the traditional vertical inlet is improved to tangential feed along the rotation direction, which enhances the forced mixing process of gas and liquid phases in the reaction space, and intensifies the micro-mixing and nucleation process of reactant ions. An inlet anti overflow device is further provided to prevent fluid from overflowing upwardly upon increasing the inlet flow volume, thereby improving product quality control and achieving effective control of particle size and distribution in nucleation while improving production efficiency and quality, obtaining products with smaller particle size and narrower distribution. The particle size of the product is controlled within the range of 15-200 nm, while the primary particle size distribution range is reduced to 30-60 nm.

A product in powder form having a dry matter content of at least 90% by weight on its total weight and containing lactose in a quantity of at least 85% by weight on its total weight, as well as having a high bulk density; moreover a process for the production of this product in powder form is disclosed, comprising the steps of vacuum-concentrating a lactose-containing liquid, mixing the so-concentrated liquid with a lactose-containing powder and with a high dry matter content and, finally, drying the so-obtained powdered mixture.
