Petroleum Coke: Industry and Environmental Issues

Notes: The process of "calcining" converts green coke to almost pure carbon, with a defined structure to produce carbon anodes for the aluminum industry. Petcoke Compared to Metallurgical Coke and Coal Petcoke has a significantly high heating value compared to metallurgical coke (metcoke) and bituminous coals (see Table 2).
