China's annual output of oil slurry is about 15 million tons, currently mainly used as low-value heavy fuel oil, coking feed or asphalt production raw materials, such as after deconsolidation treatment to different solid content/ash levels of clarified oil, can become the production of various high value-added materials of raw materials, such as to meet the market production of marine fuel, carbon black and carbon fiber raw material demand, the market prospect is broad, appreciation potential is considerable.

In contrast, in the United States market, the annual supply of oil slurry is about 20 million tons, 80% of which is used to blend heavy marine fuel oil after deconsolidation, and the rest is used as raw oil for the production of high-end carbon materials (such as special carbon black, needle coke, carbon fiber, etc.).
