How to get a unknown substance's thermophysical properties?

Hello, all foamers.
Nice day,isn't it?
In the filed of coal combustion,one of the most popular method to reduce the multi-species pyrolysis process of the particles is to approximate the volatiles as a single postulate substance: CxHyOz。Then how the thermophysical properties (specific heat, enthalpy, entropy, viscosity and thermal conductivity etc.) be calculated? In openfoam, we can use the CHEMKIN (.dat .inp files )as the input files and then use chemkinToFOAM convert the chemkin files to FOAM files (foam.dat foam.inp). Since we postulate a "new" substance (in our case:CxHyOz) , then how should i determine the the values of "x,y,z" and the properties of the "new substance"?
I implore your help. Thank you very much!

Can anyone explain me how can I introduce a new substance to openFoam (which is not compiled before), in details?
I'm working on sprayFoam solver.
I want to add liquid CH4 as the CH4 defined in src folder is in gaseous.
Also I do not know how can I find NASA Polynomials coefficients for different materials such as liquid methane?
Thanks a lot.
