WebbThe Langmuir-Hinshelwood-Hougen-Watson (LHHW) approach accounts for the surface concentrations of the species taking part in the reaction. Relating surface species to the observed species partial pressures in the gas phase provides equations that can be fitted to the kinetic data. Based on the Langmuir adsorption isotherm, the WebbA comprehensive microkinetic mechanism for the oxidative coupling of methane (OCM) was developed by using the model La2O3–CeO2 catalyst at industrially relevant conditions up to 0.9 MPa and a gas hourly space velocity (GHSV) of ∼650,000 h–1. A Langmuir–Hinshelwood (LH)-based surface mechanism was coupled with gas-phase …
