  • Type of mechanism     :  Skeletal
  • Fuels used                     :  Butane
  • Oxidizer used                 : Water
  • Number of species      :   33 + 0 QSS
  • Number of reactions    :  229
  • Cases of application    :  0D, 1D


This skeletal mechanism has been derived by Robin Campet at CERFACS.

It is derived using ARCANE from a detailed mechanism* for the pyrolysis and combustion with 451 species and 17848 reactions from Politecnico di Milano, done for propane steam cracking process, with a reasonable temperature and pressure range for steam cracking. Cases with a temperature and a pressure in [900K, 1300K] and [2e5Pa, 2.4e5Pa] respectively are validated, while larger T/P range can be expected.

The mass fraction temporal evolutions of main species butane C4H10, ethylene/ethene C2H4 , propene C3H6, methane CH4, butadiene C4H6 and hydrogen H2 are ensured.

It comprises 19 transported species, 14 QSS species (totally 33 species) and 229 reactions.

* The detailed mechanism was found with the link below:
But this link was available until 2019. Later, a new detailed mechanism has been provided on the website of CRECK Modeling at Politecnico di Milano.
