Method for calcining delayed coke (Patent) OSTI.GOV
Abstract. Delayed petroleum coke is calcined in an internally-fired vertical shaft kiln. A downwardly-moving bed of green coke is preheated in the top of the kiln by rising combustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.
Calcined Petroleum Coke Coal Tar Pitch - Rain Carbon Inc
Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a by-product of refining crude oil. While CPC can be created using a number of processes -- including rotary kiln, hearth and vertical shaft technologies -- the high-temperature conversion from green coke to calcined coke alters the material in key three ways:
