摘要： A method of flaking nano-platelets from particles of a laminar material is provided. The method comprises steps of providing a suspension of the particles of the laminar material in a liquid; and forming a flow with toroidal vortices in the suspension of the particles such that the particles are exposed to alternating flow velocities and alternating pressures. A method of separating a mixture of graphite and nano-platelets including graphene is also provided. A method of aligning nano-platelets in a suspension is also provided.

摘要： Chemical reactor with high speed rotary mixing, system thereof, and method thereof, for catalytic thermal conversion of organic (hydrocarbon-containing) materials (coal, plastics, rubber, plant matter, wood shavings, biomass, organic wastes) into diesel and other liquid fuels (automobile or/and jet engine fuels). Relevant to non-conventional commercial scale production of liquid fuels, and to commercial scale processing and disposing of organic waste materials. Chemical reactor includes: integrated combination of a reactor stationary assembly (RSA), having only stationary components remaining stationary during chemical reactor operation, and a reactor rotary mixing assembly (KRMA), having only rotatable components rotating during chemical reactor operation. May include anti-abrasion shield for shielding inner surface of reactor central housing from abrasion during chemical reactor operation. Rotor may include a reinforcement disc. Rotor blades or/and reinforcement disc may include rotor-based performance and process control structural features (openings, or/and protmsions, or/and depressions), for additionally controlling performance of the rotor.
