Shutdown of China’s Coker Facilities Creates Shortage in High-Sulphur Anode Coke Supply

Zhejiang Petrochemical has shut down its delayed coker unit, significantly impacting the supply of high-sulfur, anode-grade petroleum coke. The facility, which produced around 70,000 tons monthly with a sulfur content of 6.5%, was crucial for the anode-grade calcining market. This disruption is expected to drive demand for alternative sources, notably from U.S. Gulf refiner Motiva and Japan’s Cosmo Oil, both of which could see increased interest in their high-sulfur cokes.

Cosmo Oil’s Sakai refinery, historically focused on domestic supply, is now positioned for exports, offering high-sulfur coke to Chinese buyers at competitive prices. China has begun importing Japanese coke again, with 11,000 tons in July and 21,800 tons in August, marking a notable shift in the supply landscape. This situation is likely to elevate global anode-grade petroleum coke prices as refiners respond to China’s diminished domestic production.
