Propane combustion - reduced reaction mechanism
 
Hello,

I am looking for a reduced reaction mechanism for propane combustion (<10 steps) to be used in the chemkin file.

Does anyone know of such a reaction mechanism, or any article where it may be found?

Thanks!

Hi gk

I am also looking for a very simple mechanism. I've found detailed mechanisms (around 100 steps), but I've been unable to find a simple (<10 steps) mechanism as you say.

If you or anyone else finds a resource containing such a simple mechanism, please let me know.

Thanks
Rob

CHARLES, K. W. and J. WILLIAM (1984). "A Comprehensive Chemical Kinetic Reaction Mechanism for Oxidation and Pyrolysis of Propane and Propene." Combustion Science and Technology 37(3-4): 117-152.
it has 83 steps

if you find that(<10steps),please let me konw.

thank you

I've abandoned Chemkin, and I'm just using the following 3-step mechanism:

C3H8 + 1.5O2 -> 3CO + 4H2
CO + 0.5O2 -> CO2
H2 + 0.5O2 -> H2O

All the reaction constants come from StarCD's database, so I don't have to fill them in myself.

If you're after detailed ChemKin mechansims, then there are some for propane at these sites:

(127 species, 1200 reactions, covering reactions of C1 to C3 hydrocarbons)

Dear Rob
I tried to find propane reduced mechanisms with your links, But there is some problem with the links, For example one of them is GRI-3.0 mechanism that is for methane, the other link was not working and the third is sandiego mechanism which is not mentioned in their site that is for propane? would you plz help me?
Thanks
Babak

One of the links has expired. There's nothing I can do about that.

The GRI-3.0 mechansim has a propane submechanism within it, although it is primarily intended for simulating methane reactions.

The complete Sandiego mechanism includes propane combustion. Look here:
