“…Suppose the previous does not happen in practice; in that case, deviations may be associated with the description of chemical kinetics due to the multiple secondary reactions generated, which would cause concentration gradients at the particle scale. These gradients are also influenced by intradiffusional limitations, affecting the reactor with temperature gradients (e.g., hot spots), thus resulting in the reporting of multiple growth factors and deviations from the ideal ASF distribution. − …”

The Fischer−Tropsch technology has allowed, since its emergence a century ago, the production of stable liquid fuels from different raw materials in different geographic scenarios that do not necessarily have oil reserves. Some of these raw materials can generate high-quality fuels with a lower content of sulfur, aromatic, and heterocyclic compounds. The scaling and intensification of the reactors are essential factors in this context, and important challenges such as energy transfer due to the highly exothermic reaction, hydrodynamics due to limited information on pilot-scale in a reasonable range of conditions, or reducing CH 4 selectivity while maintaining high conversion through catalyst design, must be considered. This perspective provides an overview of recent developments in industrial-scale low-temperature Fischer−Tropsch reactors, with a focus on the significance of microchannel reactors in the scale-up process. The advancement in the Fischer−Tropsch synthesis is discussed, with an emphasis on the carbide and CO insertion mechanisms, as well as the socio-political-economic factors that continue to impact the development of this technology.
