석탄이나 다른 탄소 물질을 코크스로 만들거나(타동사), 코크스로 변하다(자동사).
To convert coal or other carbonaceous material into coke by heating it in an oxygen-deprived environment (transitive); also, for material to become converted into coke (intransitive).
예문:
"The facility was designed to coke bituminous coal efficiently to maximize yield."
"If the temperature is too high, the material might coke too quickly, resulting in a brittle product."
