Effect of Preparation Conditions of Fe@SiO₂ Catalyst on Its Structure Using High-Pressure Activity Studies in a 3D-Printed SS Microreactor.

ABSTRACT: 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). The mesoporous structure of the two catalysts, Fe@SiO₂ (OP) and Fe@SiO₂ (AC), ensured a large contact area between the reactants and the catalyst. They were characterized by N₂ physisorption, H₂ temperature-programmed reduction (H₂-TPR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron microscopy (XPS), and thermogravimetric analysis-differential scanning calorimetry (TGA-DSC) techniq
