China Petrochemical applied for a patent for pre-baked anode special petroleum coke and its preparation method, which can produce high-end petroleum coke from inferior crude oil.

financial sector on March 17, 2025, information from the State Intellectual Property Office shows that China Petroleum and Chemical Corporation has applied for a patent called "A special petroleum coke for pre-baked anodes and its preparation method", publication number CN 119614247 A, The application date is December 2024.

patent shows that the present invention belongs to the technical field of petrochemical industry, and specifically relates to a pre-baked anode special petroleum coke produced from high-sulfur high-acid crude oil and its preparation method. The preparation method of the pre-baked anode special petroleum coke described in the present invention, with high-sulfur high-metal crude oil as raw material, by decompression distillation to prepare decompression residue, and then use the demetallization agent to treat the high-sulfur high-metal decompression residue, and then the decompression residue to moderate hydrogenation treatment, and finally can obtain the metal content and low sulfur content of petroleum coke products. The preparation method of pre-baked anode special petroleum coke described in the present invention can use inferior crude oil to produce high-end pre-baked anode special petroleum coke, which not only expands the source of raw materials for petroleum coke production, but also improves the added value of inferior ethylene tar.
