On January 29, Qirun Petrochemical quoted petroleum coke at 1,600 yuan/ton, down 100 yuan/ton from the previous trading day, with sulfur content at 4.0%. The delayed coking unit has an annual capacity of 1.6 million tons and a daily output of 700 tons. PriceSeek analysis of petroleum coke, with a bullish-bearish score: -1. Qirun Petrochemical's price reduction of 100 yuan/ton to 1,600 yuan/ton represents a significant decline (5.9%), reflecting supply pressure in the spot market (daily output of 700 tons, annual capacity of 1.6 million tons) or weak demand. The price cut directly weighs on spot prices and may trigger market expectations of further declines. However, as it does not cover the entire industry benchmark price, it is rated as a moderate bearish factor (-1).
