Transformation behavior of vanadium in petroleum coke during high temperature CO 2 -gasification

The transformation of Vanadium (V) during thermal conversion of petroleum coke (petcoke) is responsible for ash-related operational problems, such as fouling, corrosion, and deposition. In this paper, The V volatilization behavior and V compounds in ashes were investigated during petcoke gasification at the temperature range of 1100–1500 °C. The occurrence modes of V in raw petcoke and their gasification residues were determined using the method...
