Sulfur removal from petroleum coke during high
The SO 2, CS 2, COS, S, and H 2 S emissions have been proposed from several petcoke calcination evaluations [4, 18, 63]. Given this low pressure the process is pyrolysis, in the present work, H 2, CO, CO 2, and several sulfur-containing compounds, such as SO 2, and CS 2, with perhaps trace amounts of COS and H 2 S, were identified …

Detailed Project Report on calcined petroleum coke
Petcoke is over 90 percent carbon and emits 5 to 10 percent more carbon dioxide (CO2) than coal on a per-unit-of-energy basis when it is burned. As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more CO2 than coal per unit of weight. The difference between coal and coke in CO2 production per unit energy produced ...

Calcined Petroleum Coke & Coal Tar Pitch
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:
