The British English spelling of carbonization; the process of converting organic material into carbon or charcoal through heating or chemical treatment.
From carbonise plus -ation (a process). The '-isation' ending is standard British English, while American English uses '-ization'.
Carbonisation is how charcoal is made—heat wood in an oxygen-free environment and the organic compounds break down, leaving almost pure carbon that's perfect for grilling or water filters.
