A Study On Thermal Combustion Of Lean Methane–Air Mixtures: Simplified Reaction Mechanism And Kinetic Equations, Krzysztof Gosiewski, Anna Pawlaczyk, Krzysztof Warmuzinski, Manfred Jaschik
Krzysztof Gosiewski
Homogeneous combustion of lean methane–air mixtures occurs in both thermal and catalytic reverse-flow reactors. The modeling and design of such reactor requires a reliable and relatively simple kinetic model of the combustion. Although a number of detailed descriptions of the kinetics of homogeneous combustion are available in the literature (including those which take into account complex free-radical reactions), their practical usefulness is doubtful. In the present study a simple one- or two-stage model is proposed which directly describes global kinetics and neglects intermediates and radicals. Special attention is paid to the mechanism of the possible formation of carbon monoxide. The …

Dynamic Modelling Of Industrial So2 Oxidation Reactors Part Ii. Model Of A Reverse-Flow Reactor, Krzysztof J. Gosiewski
Krzysztof Gosiewski
The results are presented of a computer simulation of a reverse-flow reactor. The results are compared with experimental data quoted by other workers. The necessity to take into account gas-to-catalyst heat transfer is stressed, so that quantitatively correct predictions may be obtained using the model. A brief description is given of the way flow reversal has been incorporated in the model, and the possibility of the accumulation of errors occurring during the calculations is mentioned. It is shown that the one-dimensional heterogeneous model of the bed makes it possible to analyze the process with an accuracy sufficient for the preliminary …
