Abstract A process for preparing acicular petroleum coke from sulfur-contained ordinary-pressure residual oil includes such steps as hydrorefining, hydrodemetalating, hydrodesulfurizing, separating, hydrogenating to generate hydrogenated heavy fraction oil, and delay coking in a certain condition. Its advantages are low CTE (less than 2.6X10 to the power -6/deg.C, low sulfur content (less than 0.7 wt.%) and high quality.
