This invention relates to the field of petrochemical technology, specifically to a method and apparatus for increasing the production of high-quality, low-sulfur petroleum coke. The method includes: subjecting feedstock oil and catalyst to hydrodesulfurization pretreatment; heat-treating the resulting liquid-solid component I; separating and extracting the resulting liquid-solid component II; and coking the obtained coking feedstock to obtain low-sulfur petroleum coke with a sulfur content ≤2 wt%. The catalyst is selected from at least one complex formed by the coordination bonding of an active metal and an organic ligand. The method provided by this invention not only achieves efficient conversion of feedstock oil and increases the production of high-quality petroleum coke, but also broadens the feedstock sources for low-sulfur petroleum coke, realizing the economic added value of feedstock oil, especially high-sulfur, low-quality feedstock oil.
