Z77 mechanism for kerosene combustion involves 77 reactions. However, the file is available in cantera format. Please convert in to chemkin format.I have attached the file in this question.
Dear @Louis Drebler, I have already contacted the author.he is not having chemkin file.he only shared me the cantera file.he told me to prepare the chemkin mechanism file by considering the reaction s. I tried but getting error.
I have some experience converting from chemkin to cantera .cti format, but not the other way around. However, I have found some info that may help you:
