Microkinetic modeling is powerful tool in heterogeneous catalysis, as it quantitatively merges fundamental surface chemistry principles with experimental data, avoiding the need for prior assumptions about rate-determining steps (RDS), quasi-equilibrated steps, or most abundant reaction intermediates (MARI). This project focuses on modeling of green, heterogeneously catalyzed reactions that generate H2 and syngas (H2 + CO), such as dry reforming of methane (DRM). Combining endothermic DRM with exothermic partial oxidation of methane (POM) provides an energy-efficient approach, yielding oxidative dry reforming of methane (ODRM) that boosts CH4 conversion, strengthens resistance to deactivation, and produces syngas at lower temperatures.
