Abstract Catalytic membrane reactors have the potential to render process of oxidative coupling methane economically viable. Here, results from operando XRD-CT studies three different catalytic reactors, employing BaCo0.4Fe0.4Zr0.2O3-? (BCFZ) and La0.6Sr0.4Co0.2Fe0.8O3-? (LSCF) perovskite membranes with Mn-Na-W/SiO2 La-promoted catalysts, are presented. It is shown that synchrotron X-ray tomogr...

introduction oxidative stress is an inevitable consequence of intensive production due to mismatched balance between free radical production and natural antioxidant capacity of animals. reactive oxygen species (ros) refers to a group of free radicals produced by oxidative energy cycle and also recently demonstrated to be as a weapon for macrophage cells. moreover, feed processing phenomena such...
