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 (RRMA), 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 protrusions, or/and depressions), for additionally controlling performance of the rotor.

Current chemical batch processing technology is based on batch reactors, which typically consist of a vessel, in which reactants are processed. The batch reactor comprises a reactor vessel having at least one first thermal transfer element; a removable top cover for sealing the reactor vessel; a baffle component having at least one second thermal transfer element; and an agitator component, wherein each of the at least one first thermal transfer element and the at least one second thermal transfer element is independently controllable, and wherein the batch reactor comprises a thermal transfer surface-to-volume ratio of at least 6:1. This increases the thermal transfer potential and the thermal energy transfer efficiency of the batch reactor, thereby to increase production speed and throughput.
