Claim Text:
1. A process of producing petroleum coke, said process comprising the steps: (a) obtaining a coke precursor material derived from carbonaceous origin; (b) subjecting said coke precursor material to a delayed coking process, said delayed coking process performed for sufficient time and at sufficient temperature and under sufficient pressure so as to promote the production of porous sponge petroleum coke; and (c) adding at least one chemical compound of predetermined quality and predetermined quantity to said porous sponge coke in a coke quenching portion of said delayed coking process within a coke drum pressure vessel, wherein said quenching is conducted at a temperature less than 510 degrees Centigrade; whereby said at least one chemical compound substantially improves the fuel properties, combustion characteristics, ash characteristics, or environmental impacts of said coke when used in a combustion process.
