Numerical problems in the solution of oxidation and combustion models

Faced with large and detailed kinetic schemes of pyrolysis, partialoxidation and combustion of hydrocarbon mixtures, the complex processmodels usually constitute stiff systems of both differential and coupleddifferential-algebraic equations. This paper discusses different typicalapplications of a new robust and efficient numerical integration methodto solve these problems. The examples refer to gas solid catalyticreactors, partial oxidation of...
