Abstract:
Particulate carbonaceous material, for example delayed petroleum coke, is calcined in an internally-fired vertical shaft kiln (10). 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. Partially cooled calcined coke is recovered from the bottom of the kiln.
