Title
A comparative kinetic study on the oxidative coupling of methane over LSCF perovskite-type catalyst
Abstract

A gas-phase heterogeneous kinetics is described over perovskite with formula La0.6Sr0.4Co0.8Fe0.2O3−δ (LSCF) for the oxidative coupling of methane under differential conversion conditions in a microcatalytic fixed-bed reactor. The ethane (C2H6) and carbon oxides (COX) formation and methane conversion rates were obtained as a function of methane and oxygen partial pressure under experimental conditions of: 0.20

Graphical abstractThe kinetic models of the OCM reaction were investigated over La0.6Sr0.4Co0.8Fe0.2O3−δ perovskite catalyst. Two mechanisms of Eley–Rideal type were chosen for fitting the experimental data with calculated result for methane conversion, C2H6 and COX formation rates. The kinetic parameters were estimated and compared for chosen models.Figure optionsDownload full-size imageDownload as PowerPoint slide
