1 Introduction. Petroleum coke (PC), a by-product from oil refining, is widely used in modern metallurgical industries owing to its ultra-low cost (≈200 $ t −1) and abundant resource (>28 Mt a −1 in China). [1-3] The application of PC depends on the content of sulfur, a detrimental impurity that severely impedes the performance of …

In carrying out the method, petroleum coke is first calcined by heating it to a temperature of at least about 900 C. The calcined coke is continuously delivered to a heating zone, preferably while it is still hot. The coke is heated in the heating zone by direct electrical resistance to a temperature of at least about 1700 C. If it is desired ...

Abstract. Microcrystalline cellulose was pyrolyzed and catalytically graphitized under temperatures ranging from 1000 °C to 1600 °C in the presence of nickel (Ni). Optimal conditions for graphitization were determined, along with the structure and conductivity of the resulting samples. The optimal conditions were identified as heating at 1400 ...
