The vacuum residue of petroleum is cracked and coked at 500-550 ℃ in the coking unit to produce black solid coke. It is generally believed that it is amorphous carbon, or a highly aromatic polymer carbide containing needle like or granular structure of micro graphite crystals. The hydrocarbon ratio is very high, 18-24. The relative density is 0.9-1.1, the ash content is 0.1% – 1.2%, and the volatile matter is 3% – 16%.

In 2021, China’s petroleum coke output will be 30.295 million tons, with a year-on-year growth of 3.7%; The apparent demand for petroleum coke in China was 41.172 million tons, up 9.2% year on year.

At the early stage, the coking process for producing petroleum coke at home and abroad was kettle coking or open hearth coking. At present, delayed coking is widely used. In 2021, the largest output of petroleum coke in China will be 11.496 million tons in Shandong; The output of petroleum coke in Liaoning is 3.238 million tons

According to Chinese customs data, China’s petroleum coke imports will be 12.74 million tons in 2021, up 24% year on year; The export volume was 1.863 million tons, up 4.4% year on year. In 2021, the import amount of China’s petroleum coke will be 2487.46 million US dollars, and the export amount will be 876.47 million US dollars

The properties of petroleum coke are not only related to raw materials, but also closely related to delayed coking process. In 2021, the operating rate of China’s petroleum coke will decline to 64.85%

Petroleum coke can be used in graphite, smelting and chemical industries depending on its quality. The price will rise in 2022, and will decline in June. In August 2022, the price of China’s petroleum coke will be around 4107.5 yuan/ton
