Abstract:
A method for altering coke morphology in a delayed coking process of heavy oil is provided. An effective amount of one or more oil dispersible or oil soluble polynuclear aromatic compounds, or functionalized lignin, is added or contacted with the resid or heavy oil at a point before or after the step of heating the heavy oil to coking temperatures. The addition of additives facilitates the formation of shot coke and inhibits the formation of sponge coke.
