I want to create pseudo-species about coal. Is there any tutorial to make thermo.db about pseudo-species? I know about the reaction one but when I try to find about thermo.db I cannot find it

CO + 3H2 = CH4 + H2O 2.401E+22 0.0 2.672E+4
CO2 + H2 = CO + H2O 6.713E+17 0.0 9.4108E+2
CO2 + 4H2 = CH4 + 2H2O 2.439E+23 0.0 2.515E+3
END


Note: After the reaction first numerical value is reaction constant before 0.0 and the second numerical value is activation energy
This reaction is for production of Methnol and accordingly you can write yours

Thank you for your comment. But I still confuse about the thermo one.. I found this in https://pubs.acs.org/doi/10.1021/ef200853t. But I do not know the mean. Thank you
