Analysis of non-catalytic reactions following Langmuir-Hinshelwood kinetics

Analysis and shape inequalities for gas‐solid reactions with changing volume

“…This seeming anomaly occurs because 0 is itself proportional to Da (cf. Ramachandran, 1982). The analytical bound Eq.…”

Solar Syngas Production from H2O and CO2 via Two-Step Thermochemical Cycles Based on Zn/ZnO and FeO/Fe3O4 Redox Reactions: Kinetic Analysis

“…A competitive kinetics model was used for the interface-controlled regimes for the Zn and FeO reactions with CO 2 and H 2 O. The reaction rates were represented by Langmuir−Hinshelwood kinetics, applied to describe the behavior of numerous noncatalytic gas−solid reactions . The diffusion-controlled regimes, believed to be rate-limited by ionic diffusion, were not modeled as the reaction rates were too slow for reactor design and applications.…”

Modeling of noncatalytic gas‐solid reactions

“…As strong adsorption of A on the surface of the solid reactant B is often responsible for this behavior, such systems may equally well be represented by a Langmuir-Hinshelwood kinetics. For nonlinear systems, the conversion-time relations have to be obtained by numerical integration and the methods for doing this have been described by Sohn and Szekely (1972a) for power-law kinetics and by Ramachandran (1982a) for a Langmuir-Hinshelwood kinetics.…”
