Fischer–Tropsch synthesis (FTS) in a 3D-printed stainless steel (SS) microchannel microreactor was investigated using Fe@SiO2 catalysts. The catalysts were prepared by two different techniques: one pot (OP) and autoclave (AC). mesoporous structure of the catalysts, (AC), ensured large contact area between reactants catalyst. They characterized N2 physisorption, H2 temperature-programmed reduction (H2-TPR), scanning electron microscopy (SEM), transmission (TEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), photoelectron (XPS), thermogravimetric analysis–differential calorimetry (TGA-DSC) techniques. AC catalyst had clear core–shell showed much greater surface than that OP method. activities terms FTS studied 200–350 °C temperature range at 20-bar pressure with H2/CO molar ratio 2:1. (AC) higher selectivity CO conversion to olefins (OP). Stability studies both carried out for 30 h 320 20 bar feed gas stability yielded consistent compared
