Abstract
On the basis of existing detailed kinetic schemes a general and consistent mechanism of the oxi
dation of methanol was compiled for computational studies covering a wide range of lean to rich flames. The
proposed model, featuring 21 species and 115 reactions, has been validated using three data sets and the com
puted reactants, products and intermediates mole fractions. This scheme was compared to those by
HeldâŻDryer, Egolfopolous and Pauwels under the same conditions. The developed mechanism predicts well
the concentrations of the major reactants, intermediates, and products at all the studied equivalence ratios
and it gives the best calculated values, as compared to the other used models, as well. The production rates
analysis of selected species allowed the identification of the major formation and depletion pathways. A reac
tion path analysis snowed that the main channels in methanol consumption involved H, OH and O attack and
the resulting radicals CH2OH and CH3O produced formaldehyde.
