    摘要： 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.

    摘要翻译： 提供了一种在重油延迟焦化过程中改变焦炭形态的方法。 在将重油加热至焦化温度的步骤之前或之后的时刻，将有效量的一种或多种油分散性或油溶性多核芳族化合物或官能化木质素与残油或重油相加或接触。 添加添加剂促进了焦炭的形成并抑制海绵焦炭的形成。

    摘要： A delayed coking process for making substantially free-flowing coke, preferably shot coke. A coker feedstock, such as a vacuum residuum, is heated in a heating zone to coking temperatures then conducted to a coking zone wherein volatiles are collected overhead and coke is formed. At least one polymeric additive is added to the feedstock prior to it being heated in the heating zone, prior to its being conducted to the coking zone, or both.
