The Leeds methane oxidation mechanism

The common feature of all published mechanisms is that although they are up-to-date at the time of compilation, they might become out-of-date at the time of publication and they surely become more-and-more out-of-date as the time passes. Here we are trying to maintain a methane oxidation mechanism that is always up-to-date. We are inviting everyone to criticise this mechanism (we prefer private e-mails to public criticism). This mechanism will be continously updated according to the suggestions from the chemical kinetic/combustion community and whenever new information about reactions becomes available.

In order to help checking the information in the mechanism, each reaction is annotated with a classification of the rate data (which spans from A (well know data) to U (entirely uncertain data)), an estimate of the uncertainty, the temperature interval of recommendation, and a reference to the origin of data.

A manuscript has been published in Int.J.Chem.Kinet. that contains a description of the mechanism and its testing and a comparison of selected parameters with the GRI, Warnatz, and Konnov mechanisms.

The methane mechanism has since been extended to include nitrogen and sulphur containing species.
