Abstract：Thermochemical reaction engineering is the research on the science and technology of thermochemical reactions which are induced or driven by heat. Alongside photochemical reaction engineering, electrochemical reaction engineering, catalytic reaction engineering, and polymer reaction engineering, it is a major branch of chemical reaction engineering and serves as a fundamental pillar of the interdisciplinary field of "engineering thermochemistry." Thermochemical reaction engineering finds broad applications in industries such as chemicals, energy, metallurgy, materials, environment, aerospace, and defense, with the core equipment is the thermochemical reactor. The transfer processes of momentum, mass, and heat within the reactor directly impact the efficiency of the process and the quality of the products. This study introduced five businesses that were indicative of the thermochemical reaction sector: cement manufacturing, steelmaking, carbon black production, gasification, and pyrolysis. With an emphasis on the development of crucial components such feedstock types, reactor layouts, heating techniques, and reaction mechanisms, it methodically examined the evolution of common thermochemical reactors. The study investigated how "heat" and "reaction" match at the micro, reactor, and process/system scales and how these influenced technical progress in these sectors. The results were intended to offer useful information and sources for the quick, low-carbon, and creative advancement of thermochemical reaction engineering.
