| Abstract: | The effects of NaOH concentration, leaching time, temperature, Na molar ratio of NaOH and Na2CO3 and liquid to solid mass ratio on vanadium removal, and physical chemical properties of leachate were investigated. The optimum conditions were 10 g of petroleum coke, 20 mL of oxidation, 6:1 liquid to solid ratio, 150 g/L of NaOH concentration, 62 g/L of Na2CO3 concentration, and 95°C temperature. Physical chemical properties of leachate changed along with the parameters. The microstructures of petroleum coke before and after leaching were also analyzed by scanning electron microscope. |
