Reaction amplification is not dimensional amplification, but matrix amplification. This is the core implementation method for the design of industrial-grade continuous flow reactors. Matrix amplification enables the translation of single-tube experimental data into industrial-scale applications. Therefore, the parallel reactor design arranges the reaction tubes in a matrix within the reactor to achieve the expansion of reaction channels while effectively avoiding the amplification effect. The parallel reaction employs a converging mixing tube manifold, which can be filled with catalysts, designed with a dispersion structure, and disassembled. Additionally, the parallel rotary plug flow reactor allows for the unclogging of reaction tubes, while the parallel internal turbulence reactor facilitates the flexible replacement of internal lining components.
