Impact Petroleum Cokes
USA1
Processes are provided for the oxidative solubilization of metalcontaining petroleum cokes in a basic aqueous solution, so as to segregate a solid metalcontaining residue from a solubilized and demineralized organics fraction. Oxidation conditions are provided that optimize the yield of soluble partial oxidation products and minimize the generation of CO 2 .

An EXAFS and XANES Study of V, Ni and Fe Speciation in ...
Industrial petroleum cokes with high S and containing V, Ni and Fe were analysed by XANES and EXAFS. XANES spectra were compared with standards. EXAFS was used to compare the impurity metal structures with known crystal structures. V is present largely as hexagonal V 3 S 4. Ni is present largely as hexagonal NiS. Fe is present as hexagonal FeS. 2 These compounds all have only short range .

Petroleum Coke
Petroleum coke (petcoke) is a byproduct of the oil refining process. As refineries worldwide seek to operate more efficiently and extract more gasoline and other high value fuels from each barrel of crude oil, a solid carbon material known as petcoke is produced. The physical and chemical characteristics of petcoke are a function of the crude oil and refining technology used by the refinery ...

Hydrodesulfurization of Petroleum Coke
desulfurizing green petroleum cokes such as solvent extraction, thermal desulfurization, and hydrodesulfurization. Solvent extraction can contaminate the coke. Thermal approach requires higher calcination temperatures leading to greater energy consumption and increases coke porosity. Hydrodesulfurization seems to be a viable option and was investigated in this study. The effect . of . .

Green petroleum coke is produced as a byproduct of petroleum refining. It is produced by delayed coking or by fluid coking. Petroleum coke has a weak amorphous structure. In green coke, the pores of the matrix are filled with a hardened residuum remaining from the coker feed [5, 14, 15]. Cokes obtained from high asphaltenes feedstock contain higher concentrations of sulfur and metals than ...

Petroleum Coke
Petroleum coke can be fired in combination with coals or heavy oils in circulating fluidized bed boilers; alternatively, it can be fired as the sole fuel. Some examples of petroleum coke firing in fluidized bed boilers are shown in Table Other examples of CFB boilers firing petroleum coke alone or in combination with other fuels include installations at the Nova Scotia Power Pt.
