Multi-Scale Studies of 3D Printed Mn–Na–W/SiO2 Catalyst for Oxidative Coupling of Methane

This work presents multi-scale approaches to investigate 3D printed structured Mn–Na–W/SiO2 catalysts used for the oxidative coupling of methane (OCM) reaction. The performance has been compared their conventional analogues, packed beds pellets and powder. physicochemical properties were investigated using scanning electron microscopy, nitrogen adsorption X-ray diffraction (XRD). Performance durability tests conducted in laboratory a miniplant under real reaction conditions. In addition, synchrotron-based computed tomography technique (XRD-CT) was employed obtain cross sectional maps at three different positions selected within catalyst body during OCM revealed evolution active phases silica support on spatial temporal scales interiors operating These results accompanied with SEM-EDS analysis that indicated homogeneous distribution particles across support.
