Modelling of Microchannel Reactors for Fischer-Tropsch Synthesis

The Fischer-Tropsch synthesis is an important step in coal liquefaction,natural gas liquefaction,and biomass liquefaction.In recent years,the use of microchannel reactors for Fischer-Tropsch synthesis has received widespread attention.Since thermocouples and other sensors cannot be placed easily in a microchannel reactor,it is very vital to establish a model to provide calculated results highly compatible with the experimental data.This paper mainly introduces the establishment and solution of microchannel reactor models for Fischer-Tropsch synthesis.General mass transfer differential equations,heat transfer differential equations and related parameters(such as reaction rates,dispersion coefficient,and convective heat transfer coefficient)are listed.To solve the models,numerical solutions,such as the CFD simulation methods and the programming methods,are reviewed.It is recommended that a more accurate solution strategy is the combination of CFD simulation and programming methods.
