Statistical distribution of the relative error over the 823 experimental data points for the main pyrolysis products (H₂, CH₄), combustion products (H₂O, CO, CO₂), and reactants (O₂) in combustion and pyrolysis of CH₃OH, CH₄, H₂, HCN, and C₂H₅OH. For some points, CO and H₂O are reactants (condition 13 of Table A.1). Each color gathers all molar fraction measurements of the corresponding species. Contribution from combustion and pyrolysis data are shown separately in Figs. C.3 and C.4.
