WebMar 16, 2024 · (3) “Coke burning temperature” was defined as the central temperature of DTG curves for coke combustion, and was represented by T Coke parameter. It was employed to characterize coke location on the spent ZSM-5 zeolites. Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker …
