CFD study on microchannel reactor operating conditions for Fischer-Tropsch synthesis with Fe-based catalysts.

ABSTRACT: Based on the kinetics of Fischer-Tropsch synthesis and computational fluid dynamics, this study established a numerical model for a coated microchannel reactor. The simulation results revealed the distribution characteristics of the flow fields within the reactor, demonstrating that the pressure drop in the microchannel reactor was only 3-5 Pa, with minor backmixing and potential hot spots observed near the inlet and outlet regions. Under the conditions of an inlet temperature of 340 °C, a gauge pressure of 0.7 MPa, and an H₂/CO feed ratio of 2/3, the reactor with catalyst coating on both the inner and outer surfaces of the channels exhibited a maximum temperature increase of 9.1 °C and an 8.9% improvement in CO conversion compared to the reactor with only internal channel coati
